Description

Technical Field

[0001] This invention relates to the field of mineral exploration technology, and in particular to a method and apparatus for identifying porphyry copper-molybdenum deposits. Background Technology

[0002] Porphyry copper-molybdenum deposits are the most important type of deposits for strategically scarce copper and molybdenum minerals. However, the supply situation of strategic key mineral resources such as copper and molybdenum is becoming increasingly severe. Strengthening the metallogenic research and prospecting of porphyry copper-molybdenum deposits is of great strategic significance for enhancing the country's resource security capabilities.

[0003] However, previous studies have not paid enough attention to the mineralization and enrichment patterns of strategic key minerals such as porphyry copper-molybdenum deposits, and related metallogenic theories are also relatively weak. This has resulted in low accuracy in existing porphyry copper-molybdenum deposit identification processes and poor accuracy in target area determination. Therefore, an effective solution is urgently needed to address these problems. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides a method and apparatus for determining porphyry copper-molybdenum deposits.

[0005] In a first aspect, the present invention provides a method for identifying porphyry copper-molybdenum deposits, comprising: Based on the pre-determined prospecting direction and mineralization potential of porphyry copper-molybdenum deposits, target areas where the porphyry copper-molybdenum deposits are suspected to exist are identified. Using a first-scale geological survey method, the planar distribution of geological bodies in the target area is depicted, and the concealed rock masses and related metallogenic geological bodies in the target area are predicted to determine the metallogenic areas within the target area. Based on the predetermined mineralization model of the porphyry copper-molybdenum deposit, prospecting indicators are determined. The mineralization model includes the spatial model of each target ore body in the ore body composition of the porphyry copper-molybdenum deposit, as well as the electrical structural characteristics of the porphyry copper-molybdenum deposit. Drilling is conducted on the ore body targets corresponding to the prospecting markers within the metallogenic area to verify whether the ore body targets are potential mineralization target areas for the porphyry copper-molybdenum deposit.

[0006] In some embodiments, the process of determining the prospecting direction of the porphyry copper-molybdenum deposit includes: Geological surveys were conducted in areas where known porphyry copper-molybdenum deposits exist, revealing the geological conditions necessary for the development of such porphyry copper-molybdenum deposits. The deposit characteristics of the known porphyry copper-molybdenum deposit were explored to obtain the mineralization model of the porphyry copper-molybdenum deposit; Based on the geological conditions, the metallogenic theory of the porphyry copper-molybdenum deposit, and the metallogenic model, the prospecting direction of the porphyry copper-molybdenum deposit is determined, wherein the upper part of the deposit is a skarn-type deposit and the lower part is a porphyry-type deposit.

[0007] In some embodiments, the deposit characteristics include ore body characteristics, ore characteristics, mineral characteristics, and geological body characteristics; the metallogenic model also includes the ore body composition, ore variation law, mineral composition, and mineral property characteristics of each mineral in the porphyry copper-molybdenum deposit. The process of detecting the deposit characteristics of the known porphyry copper-molybdenum deposit to obtain the mineralization model of the porphyry copper-molybdenum deposit includes: The orebody characteristics of the known porphyry copper-molybdenum deposit are explored to determine the orebody composition of the porphyry copper-molybdenum deposit and the spatial model of each target orebody in the orebody composition; The ore characteristics of the known porphyry copper-molybdenum deposits are investigated to determine the ore variation patterns of the porphyry copper-molybdenum deposits; The mineral characteristics of the known porphyry copper-molybdenum deposit are detected to determine the mineral composition of the porphyry copper-molybdenum deposit and the mineral property characteristics of each mineral in the mineral composition; The geological features of the known porphyry copper-molybdenum deposits were investigated to determine their electrical structural characteristics.

[0008] In some of these embodiments, the ore body is composed of an upper skarn type and a lower porphyry type; The spatial model of the skarn type is a spatial metallogenic theoretical model for skarn-type deposits; The spatial model of the porphyry type is a theoretical model of spatial zoning of porphyry type deposits; The electrical structural feature is that, in the vertical direction of the geological body of the porphyry copper-molybdenum deposit, the resistivity exhibits a three-layer electrical structural feature with high resistivity at the top and bottom and low resistivity in the middle.

[0009] In some embodiments, determining prospecting indicators based on a predetermined porphyry copper-molybdenum deposit mineralization model includes: Based on the spatial metallogenic theoretical model of the skarn-type deposit, the spatial zonation theoretical model of the porphyry-type deposit, and the three-layer electrical structure characteristics, geophysical exploration at a second scale is conducted on the metallogenic region to obtain the prospecting indicators, wherein the first scale is smaller than the second scale.

[0010] In some of these embodiments, the ore variation pattern is such that the porphyry copper-molybdenum deposit, from shallow to deep, is successively lead-zinc mineralization, copper mineralization, copper-molybdenum mineralization, and molybdenum mineralization.

[0011] In some of these embodiments, the mineral composition includes pyrite, chalcopyrite, magnetite, molybdenite, galena, and sphalerite.

[0012] In some of these embodiments, the mineralization potential is that the mineralization source region has crust-mantle mixing characteristics.

[0013] In some embodiments, the geological survey method of the first scale includes at least one of geological survey, gravity survey, magnetic survey, and electrical survey.

[0014] Secondly, the present invention also provides an apparatus for identifying porphyry copper-molybdenum deposits, comprising: The first determining module is configured to determine the target area where the porphyry copper-molybdenum deposit is suspected to exist based on the pre-determined prospecting direction and mineralization potential of the porphyry copper-molybdenum deposit. The second determining module is configured to characterize the planar distribution of geological bodies in the target area and predict concealed rock masses and related metallogenic geological bodies in the target area through geological surveying at a first scale, thereby determining the metallogenic areas within the target area. The third determining module is configured to determine prospecting indicators based on a pre-determined ore-forming model of the porphyry copper-molybdenum deposit. The ore-forming model includes a spatial model of each target ore body in the ore body composition of the porphyry copper-molybdenum deposit, as well as the electrical structural characteristics of the porphyry copper-molybdenum deposit. The fourth determination module is configured to perform drilling verification on the ore body target corresponding to the prospecting marker in the metallogenic area to determine whether the ore body target is a potential mineralization target area of ​​the porphyry copper-molybdenum deposit.

[0015] Thirdly, the present invention also provides an electronic device, including a memory and a processor, wherein the memory stores a computer program, and the processor is configured to run the computer program to implement the method for determining porphyry copper-molybdenum deposits as described in the first aspect above.

[0017] Fifthly, the present invention also provides a computer program product, including a computer program that, when executed by a processor, implements the method for determining porphyry copper-molybdenum deposits as described in the first aspect above.

[0018] Compared with existing technologies, the method and apparatus for determining porphyry copper-molybdenum deposits provided by this invention, by pre-determining the prospecting direction and mineralization potential of porphyry copper-molybdenum deposits, identifies target areas where the porphyry copper-molybdenum deposits are suspected to exist, thus narrowing the scope of determination to a certain extent; then, by using a first-scale geological survey method, the planar distribution of geological bodies in the target area is depicted and the concealed rock masses and related mineralized geological bodies in the target area are predicted, thus determining the mineralized areas within the target area, further narrowing the scope of determination of porphyry copper-molybdenum deposits; Furthermore, based on the pre-determined mineralization model of the porphyry copper-molybdenum deposit, namely the spatial model of each target ore body in the ore body composition of the porphyry copper-molybdenum deposit, and the electrical structural characteristics of the porphyry copper-molybdenum deposit, prospecting indicators are determined, improving the accuracy of the prospecting indicators. On this basis, drilling verification is carried out on the ore body targets corresponding to the prospecting indicators in the mineralization area to determine whether the ore body targets are potential mineralization target areas of the porphyry copper-molybdenum deposit. This improves the accuracy of the porphyry copper-molybdenum deposit determination process and enhances the accuracy and reliability of the porphyry copper-molybdenum deposit determination results.

[0027] The following is combined Figures 1 to 3 The present invention describes a method and apparatus for determining porphyry copper-molybdenum deposits.

[0028] Figure 1 This is one of the flowcharts illustrating the method for determining porphyry copper-molybdenum deposits provided by the present invention, such as... Figure 1 As shown, the method for identifying this porphyry copper-molybdenum deposit includes the following steps: Step 101: Based on the pre-determined prospecting direction and mineralization potential of porphyry copper-molybdenum deposits, identify target areas where the porphyry copper-molybdenum deposits are suspected to exist.

[0029] Specifically, the prospecting method includes mineralization direction (where to look) and prospecting method / technical route (how to look). Mineralization direction is used to characterize the favorable target area, stratum, structural zone, or possible extension trend of the ore body that the prospecting work should target.

[0030] For example, the prospecting direction is that the upper part of the deposit is a skarn-type deposit and the lower part is a porphyry-type deposit (i.e., shallow skarn-type deposit + deep porphyry-type deposit).

[0031] Specifically, mineralization potential is used to characterize the likelihood of a region (or a certain rock or stratum) forming mineral resources under current knowledge and conditions, as well as the total amount of mineral resources that may be contained therein.

[0032] For example, the mineralization potential is that the mineralization source region has crust-mantle mixing characteristics.

[0033] Specifically, the target area is the region where porphyry copper-molybdenum deposits may exist.

[0034] In practical applications, target areas that meet the prospecting direction and mineralization potential of porphyry copper-molybdenum deposits can be selected from the study area according to the prospecting direction and mineralization potential. That is, the source area of ​​the mineralization in the target area has crust-mantle mixing characteristics, and the upper part of the deposit in the target area is a skarn-type deposit, while the lower part of the deposit is a porphyry-type deposit. In this way, the scope of determination of porphyry copper-molybdenum deposits can be narrowed to a certain extent.

[0035] It should be noted that investigations of known porphyry copper-molybdenum deposits suggest that, in terms of mineralization potential, the source areas of the ore-forming materials exhibit crust-mantle mixing characteristics. Regarding prospecting direction, the main polymetallic components, including copper and molybdenum, originate from magmatic evolution, with a tendency towards porphyry-type mineralization at depth. Fluid inclusion characteristics indicate that fluid evolution is still between the porphyry and skarn stages, and the highest fluid inclusion temperature is lower than the main mineralization temperature of the porphyry molybdenum deposit, indicating significant prospecting potential at depth and in the periphery. The concealed porphyry bodies are large in scale, possessing the potential to form super-large porphyry copper deposits and ore clusters, offering broad prospecting prospects. Therefore, exploration can be conducted around the already discovered Xiangkuang porphyry body system, or similar deposits can be explored around regional metallogenic belts to advance further prospecting work.

[0036] Exploration deployment should be carried out around the discovered Xiangkuang porphyry body system: For the local Xiangkuang porphyry body where thick ore bodies have been discovered, compared with the zonal characteristics of the porphyry deposit metallogenic system, it is necessary to combine the morphology and scale characteristics of the concealed rock body reflected by geophysics, increase the spacing of the drilling projects, and gradually increase the density of the project deployment based on a general understanding of the overall scale of the ore body.

[0037] Exploration efforts are being conducted around the regional metallogenic belt to identify similar deposits: The region not only shares the same tectonic framework as the Xiangkuang area but also features a wide range of contemporaneous intermediate-acidic porphyry bodies. Furthermore, previous gravity and magnetic anomalies indicate the presence of several similarly sized concealed to semi-concealed intrusive bodies or stocks, whose magma source regions, emplacement ages, geochemical characteristics, and surrounding rock conditions are highly similar to those of the area where this discovery was made. Therefore, the region possesses favorable metallogenic geological conditions and the potential for porphyry-type deposit formation.

[0038] Step 102: Using a geological survey method with a first scale, the planar distribution of geological bodies in the target area is depicted, and the concealed rock masses and related metallogenic geological bodies in the target area are predicted to determine the metallogenic areas within the target area.

[0039] Specifically, the first scale is a small scale, and the geological measurement methods of the first scale include at least one of geological measurement, gravity measurement, magnetic measurement and electrical measurement.

[0040] Specifically, the mineralization region refers to an area within the target region that is conducive to the formation of porphyry copper-molybdenum deposits, and the mineralization region is smaller than or equal to the target region.

[0041] In practical applications, at least one of the following methods can be used: small-scale geological surveying, gravity surveying, magnetic surveying, electrical surveying, etc., to depict the distribution of various exposed or concealed geological bodies in the target area on a macroscopic scale, to predict the spatial distribution of concealed rock masses and other related ore-forming geological bodies, and to delineate favorable ore-forming areas, thereby determining the ore-forming area and further narrowing down the scope of determination of porphyry copper-molybdenum deposits.

[0042] Step 103: Based on the predetermined mineralization model of the porphyry copper-molybdenum deposit, determine the prospecting indicators. The mineralization model includes the spatial model of each target ore body in the ore body composition of the porphyry copper-molybdenum deposit, as well as the electrical structural characteristics of the porphyry copper-molybdenum deposit.

[0043] Specifically, mineral exploration indicators refer to various phenomena and clues that can directly or indirectly indicate the existence or potential existence of mineral deposits in geological prospecting work.

[0044] Optionally, the mineralization model of porphyry copper-molybdenum deposits includes at least a spatial mineralization theory model of skarn-type deposits, a spatial zoning theory model of porphyry-type deposits, and (three-layer) electrical structure characteristics.

[0045] Optionally, the ore body consists of an upper skarn type and a lower porphyry type. The target ore body is, for example, a skarn type and / or a porphyry type.

[0046] In practical applications, mineralization models of porphyry copper-molybdenum deposits can be used to conduct large-scale geological and geophysical work in the target area to identify mineral exploration indicators.

[0047] Step 104: Drill and verify the ore body target corresponding to the prospecting marker in the metallogenic area to determine whether the ore body target is a potential mineralization target area of ​​the porphyry copper-molybdenum deposit.

[0048] In practical applications, after identifying mineral exploration indicators, ore body targets are located within the metallogenic area based on these indicators. Then, drilling is conducted to verify the ore body targets, which can effectively and accurately verify whether the ore body targets are porphyry copper-molybdenum deposits.

[0049] The method for identifying porphyry copper-molybdenum deposits provided by this invention first determines the target area where porphyry copper-molybdenum deposits are suspected to exist by pre-determining the prospecting direction and mineralization potential of porphyry copper-molybdenum deposits, thus narrowing the scope of porphyry copper-molybdenum deposit identification to a certain extent. Then, by using a first-scale geological survey method, the planar distribution of geological bodies in the target area is depicted, and the concealed rock masses and related mineralized geological bodies in the target area are predicted to identify the mineralization area within the target area, further narrowing the scope of porphyry copper-molybdenum deposit identification. Furthermore, based on a pre-determined mineralization model of porphyry copper-molybdenum deposits, prospecting indicators are identified, improving the accuracy of the prospecting indicators. On this basis, the ore body targets corresponding to the prospecting indicators in the mineralization area are drilled for verification to determine whether the ore body targets are potential mineralization target areas for porphyry copper-molybdenum deposits. This method improves the accuracy of the porphyry copper-molybdenum deposit identification process and the accuracy and reliability of the identification results.

[0050] In some embodiments, the process of determining the prospecting direction of the porphyry copper-molybdenum deposit includes: Geological surveys were conducted in areas where known porphyry copper-molybdenum deposits exist, revealing the geological conditions necessary for the development of such porphyry copper-molybdenum deposits. The deposit characteristics of the known porphyry copper-molybdenum deposit were explored to obtain the mineralization model of the porphyry copper-molybdenum deposit; Based on the geological conditions, the metallogenic theory of the porphyry copper-molybdenum deposit, and the metallogenic model, the prospecting direction for the porphyry copper-molybdenum deposit is determined.

[0051] Specifically, the known porphyry copper-molybdenum deposits refer to the porphyry copper-molybdenum deposits that have been identified.

[0052] Specifically, geological conditions refer to the geological understanding of known porphyry copper-molybdenum deposit areas, i.e., regional geological understanding.

[0053] In practical applications, geological surveys can be conducted in areas where known porphyry copper-molybdenum deposits are located to determine the strata, rock masses, and topography associated with the mineralization of known porphyry copper-molybdenum deposits.

[0054] The strata associated with mineralization are mainly the Nanzhuang Formation and Xiangkuang Formation of the Neoproterozoic Penglai Group. The Nanzhuang Formation is a suite of argillaceous clastic rocks, with lithology mainly consisting of thick-bedded yellowish-green slate interbedded with phyllite, sericite-chlorite marble interbedded with calcareous slate, yellowish-green slate interbedded with calcareous slate, and marl. The Xiangkuang Formation is a suite of carbonate rocks, with the lower part consisting of thin-bedded argillaceous limestone interbedded with slate, and the upper part consisting of thin-bedded argillaceous limestone, medium-thick-bedded limestone, and dolomitic limestone.

[0055] The rock bodies associated with mineralization are mainly late Mesozoic Yanshanian shallow to ultra-shallow intrusive rocks, primarily composed of granodiorite porphyry and contemporaneous subvolcanic rocks, such as brecciated dacite porphyry and rhyolitic dacite porphyry. Among these, granodiorite porphyry is most closely related to mineralization and is the main mineralizing geological body.

[0056] The topography associated with mineralization is a pull-apart basin with well-developed fault structures, which can be classified into near-east-west, northeast-east, and northeast-trending faults according to their strike. Among them, the near-east-west trending faults are pre-mineralization faults; the northeast-east trending faults were formed in the early Yanshanian period and their intersection with the near-east-west trending faults controlled volcanic magmatic activity and mineralization; the northeast-trending faults are extensional-shear faults and are post-mineralization faults.

[0057] Thus, based on the known strata, rock masses, and topography associated with porphyry copper-molybdenum deposits, the geological conditions for forming porphyry copper-molybdenum deposits are determined.

[0058] Specifically, the deposit characteristics include ore body characteristics, ore characteristics, mineral characteristics, and geological body characteristics. The mineral characteristics are used to characterize the minerals in the ore, and the geological body characteristics are used to characterize the vertical layering structure and electrical differences of the geological body.

[0059] In practical applications, known porphyry copper-molybdenum deposits can be explored from four levels: ore body characteristics, ore characteristics, mineral characteristics, and geological body characteristics, to obtain porphyry copper-molybdenum deposit mineralization models. This makes the mineralization models more accurate and reliable.

[0060] Specifically, metallogenic theory is the study of the geological conditions, controlling factors, spatiotemporal distribution patterns, and genetic mechanisms of mineral deposit formation. It explains how elements such as metals are activated, migrated, and ultimately enriched into minerals from the Earth's crust. It serves as the theoretical map and scientific compass for mineralization prediction and mineral exploration.

[0061] In practical applications, the mineralization theory of porphyry copper-molybdenum deposits can be obtained from relevant literature on porphyry copper-molybdenum deposits.

[0062] It should be noted that geological conditions, metallogenic models, and metallogenic theories can be determined separately in a certain order, or they can be determined simultaneously. This invention does not impose any limitations on this.

[0063] Furthermore, based on geological conditions (regional geological understanding), metallogenic models, and metallogenic theories, the direction of mineral exploration is determined. The direction of mineral exploration can be generally divided into two categories: skarn-type deposits located near the contact zone in the upper (shallow) part and porphyry-type deposits in the lower (deep) part. That is, shallow skarn-type deposits + deep porphyry-type deposits.

[0064] In this embodiment of the invention, the prospecting direction is determined from three levels: geological conditions, metallogenic theory, and metallogenic model of porphyry copper-molybdenum deposits. This effectively ensures the accuracy and comprehensiveness of the prospecting direction. Therefore, the determination of porphyry copper-molybdenum deposits based on the prospecting direction is conducive to improving the efficiency and accuracy of the determination of porphyry copper-molybdenum deposits, thereby reducing manpower and material resources.

[0065] In some embodiments, the mineralization model further includes the orebody composition, ore variation patterns, mineral composition, and mineral property characteristics of each mineral in the porphyry copper-molybdenum deposit; the step of detecting the deposit characteristics of the known porphyry copper-molybdenum deposit to obtain the mineralization model of the porphyry copper-molybdenum deposit includes: The orebody characteristics of the known porphyry copper-molybdenum deposit are explored to determine the orebody composition of the porphyry copper-molybdenum deposit and the spatial model of each target orebody in the orebody composition; The ore characteristics of the known porphyry copper-molybdenum deposits are investigated to determine the ore variation patterns of the porphyry copper-molybdenum deposits; The mineral characteristics of the known porphyry copper-molybdenum deposit are detected to determine the mineral composition of the porphyry copper-molybdenum deposit and the mineral property characteristics of each mineral in the mineral composition; The geological features of the known porphyry copper-molybdenum deposits were investigated to determine their electrical structural characteristics.

[0066] Specifically, the ore body is composed of an upper skarn type and a lower porphyry type; the spatial model of the skarn type is a spatial mineralization theory model of skarn type deposits; and the spatial model of the porphyry type is a spatial zoning theory model of porphyry type deposits.

[0067] In practical applications, the orebody characteristics of known porphyry copper-molybdenum deposits were explored, identifying a copper orebody with a maximum cumulative thickness of 191.92 meters in a single borehole, accompanied by various important resources such as molybdenum, silver, sulfur, cadmium, and gallium. The known porphyry copper-molybdenum deposits exhibit stable orebodies, displaying a two-layer mineralization structure of "upper skarn type + lower porphyry type," meaning the orebody consists of an upper skarn type and a lower porphyry type.

[0068] The lower porphyry orebody represents the main mineralization type of known porphyry copper-molybdenum deposits. It is strictly hosted within deep porphyry bodies and controlled by the morphology of the rock mass and its internal fracture system. The orebody exhibits a stable, thick, plate-like occurrence, controlled by the morphology of the deep porphyry body. The explored length of the lower porphyry orebody is 1250 meters, with a dip depth of 280 meters and a burial depth of approximately 800-1350 meters. The copper mineralization shows good continuity, with an average thickness of 102.88 meters and an average grade of 0.32%. The delineated molybdenum orebody has an average thickness of 22.25 meters and an average grade of 0.06%. The orebody is not enclosed. Therefore, the spatial model of the lower porphyry orebody is a theoretical model for the spatial zoning of porphyry deposits.

[0069] The upper skarn-type orebody is mainly hosted in and near the contact zone between the intrusive body and the Nanzhuang and Xiangkuang Formations of the Penglai Group. It is strictly controlled by the contact zone, striking at 50–60° and dipping southeast. Currently, the controlled blank area of ​​the upper skarn-type orebody is 1054m long, with a maximum controlled depth of 900m (showing a strong lateral dip trend), and an elevation of -116 to -750m, connecting with the shallow orebody within the established mining rights area. The average thickness of the orebody is 13.92m, and the average copper grade is 0.46%. The orebody is not enclosed. Therefore, the spatial model of the upper skarn-type orebody can be considered the spatial metallogenic theoretical model for skarn-type deposits.

[0070] Specifically, the ore variation pattern is that the porphyry copper-molybdenum deposit, from shallow to deep, is successively lead-zinc mineralization, copper mineralization, copper-molybdenum mineralization, and molybdenum mineralization.

[0071] In practical applications, the ore characteristics of known porphyry copper-molybdenum deposits are explored to determine that the ore characteristics exhibit a regular change from shallow to deep: "lead-zinc mineralization—copper mineralization—copper-molybdenum mineralization—molybdenum mineralization," which is the ore change pattern.

[0072] The main metallic mineral components in the ore are pyrite, chalcopyrite, galena, sphalerite, and molybdenite. The ore structure is predominantly granular, with a subhedral to anhedral granular structure in the shallower parts and anhedral granular structure in the deeper parts. The ore texture is mainly characterized by disseminated and veinlet patterns. Alteration from the interior to the exterior of the rock mass generally follows a pattern of "silicification and kaolinization → silicification, sericitization, potassic alteration → skarnification → chloritization, epidote alteration, sericitization, carbonatization, etc." Skarnification, potassic alteration, silicification, and sericitization are closely related to polymetallic mineralization. Associated beneficial components include silver, sulfur, molybdenum, and gallium, with average grades of 4.16 grams per tonne (g / t), 3.98%, 0.02%, and 0.0018%, respectively.

[0073] In practical applications, mineral analysis is performed on known porphyry copper-molybdenum deposits to determine that the main ore minerals of porphyry copper-molybdenum deposits include pyrite, chalcopyrite, magnetite, molybdenite, galena, and sphalerite, thus obtaining the mineral composition.

[0074] Then, mineral analysis was performed on each of the pyrite, chalcopyrite, magnetite, molybdenite, galena, and sphalerite to obtain the mineral property characteristics of each mineral in the mineral composition.

[0075] Pyrite is light yellow, mostly anhedral granular, with a few subhedral cubic, and a grain size mostly between 0.05 and 2 mm. It is mostly distributed along fractures in vein-like, banded, or sparsely disseminated patterns, and locally in a disseminated or speckled pattern. Some pyrite in porphyry ore bodies exhibit the following characteristics: well-developed internal fractures, some of which are filled with chalcopyrite and galena; encased in chalcopyrite, containing a large amount of small magnetite grains, and locally replaced by chalcopyrite.

[0076] Chalcopyrite is copper-yellow in color and is mostly anhedral granular with a grain size of 0.01–0.4 mm. It is often distributed as star-shaped spots, sparsely disseminated, or vein-like along micro-cracks, and some forms irregular agglomerates. Some are distributed between pyrite grains or around the edges of pyrite grains, and some are spherical or droplet-like replacements of pyrite.

[0077] Magnetite is grayish with a slight brownish tinge, and is anhedral granular with a grain size mostly ranging from 0.01 to 0.25 mm. Most magnetite is distributed in agglomerated aggregates, while a few are distributed in vein-like patterns.

[0078] Molybdenite is grayish-white, subhedral, foliate or scaly, with a diameter of 0.02–0.2 mm, and is distributed in banded aggregates or sporadically. Galena is grayish-white, anhedral granular, with a grain size of 0.05–0.5 mm, and has low hardness. Some galena contains visible black triangular pores and is mostly distributed between pyrite grains or along pyrite fissures.

[0079] Sphalerite is dark gray, anhedral granular, with a grain size of 0.2–1.5 mm, and often contains star-shaped chalcopyrite.

[0080] Specifically, the electrical structural feature is that, in the vertical direction of the geological body of the porphyry copper-molybdenum deposit, the resistivity exhibits a three-layer electrical structural feature with high resistivity at the top and bottom and low resistivity in the middle.

[0081] In practical applications, by utilizing the vertical layered structure of geological bodies and their electrical differences, controlled-source audio-frequency magnetotelluric sounding or similar electrical methods are used to characterize the morphology of concealed rock masses and other geological bodies. The resistivity generally exhibits a three-layered electrical structure characterized by "high at the top and bottom and low in the middle". The two areas with large resistivity changes at the top and bottom are favorable locations for the occurrence of two types of ore bodies. That is, in the vertical direction, the resistivity in the middle of the geological body is lower than that in the upper and lower parts.

[0082] It should be noted that the ore body characteristics, ore characteristics, mineral characteristics, and geological body characteristics can be detected separately in a certain order, or they can be detected simultaneously. This invention does not impose any limitations on this.

[0083] In this embodiment of the invention, the mineralization model is determined from four dimensions: ore body characteristics, ore characteristics, mineral characteristics, and geological body characteristics of porphyry copper-molybdenum deposits. This effectively ensures the accuracy and comprehensiveness of the mineralization model. Therefore, the determination of porphyry copper-molybdenum deposits based on the mineralization model is beneficial to improving the efficiency and accuracy of the determination of porphyry copper-molybdenum deposits, thereby reducing manpower and material resources.

[0084] In some embodiments, determining prospecting indicators based on a predetermined porphyry copper-molybdenum deposit mineralization model includes: Based on the spatial metallogenic theoretical model of the skarn-type deposit, the spatial zonation theoretical model of the porphyry-type deposit, and the three-layer electrical structure characteristics, geophysical exploration at a second scale is conducted on the metallogenic region to obtain the prospecting indicators, wherein the first scale is smaller than the second scale.

[0085] Specifically, the second scale is a large scale. The three-layer electrical structure characteristics are also known as the three-layer electrical structure characteristics of electrical sounding.

[0086] In practical applications, known elements such as the spatial zonation theory model of porphyry deposits, the spatial metallogenic theory model of skarn deposits, and the three-layer electrical structure characteristics (electrical sounding) can be used to carry out large-scale geological and geophysical work in the metallogenic area and determine mineral exploration indicators.

[0087] In this embodiment of the invention, mineral exploration indicators are comprehensively determined by using spatial zonation theory models of porphyry deposits, spatial metallogenic theory models of skarn deposits, and three-layer electrical structure characteristics. This ensures the accuracy of the mineral exploration indicators, and further, based on these indicators, the target ore body can be located. Drilling can effectively achieve precise verification.

[0088] The following is combined Figure 2 The method for determining porphyry copper-molybdenum deposits provided by this invention will be further explained.

[0089] Figure 2 This is the second schematic flowchart of the method for determining porphyry copper-molybdenum deposits provided by this invention. Figure 2 As shown, the method for identifying this porphyry copper-molybdenum deposit includes the following steps: Based on regional geological understanding, metallogenic theory and metallogenic model, a comprehensive study is conducted to determine the direction of mineral exploration. The direction of mineral exploration can be divided into two categories: skarn-type deposits located near the contact zone in the upper part and porphyry-type deposits in the lower part. Based on the prospecting direction and metallogenic potential, target areas suspected of containing porphyry copper-molybdenum deposits were identified in the study area. We will use small-scale geological surveying, gravity surveying, magnetic surveying, electrical surveying and other working methods to depict the distribution of various exposed or concealed geological bodies in the target area on a macroscopic scale (i.e., macroscopic depiction of the planar distribution of geological bodies), carry out spatial distribution prediction of concealed rock masses and related metallogenic geological bodies, and delineate favorable metallogenic areas (metallogenic regions). After the favorable metallogenic areas are delineated, the favorable mineral-bearing locations are determined. This involves using known elements such as the spatial zonation theory model of porphyry deposits, the spatial metallogenic theory model of skarn deposits, and the three-layer electrical structure characteristics of electrical sounding, to carry out large-scale geological and geophysical work and determine the mineral exploration indicators. Furthermore, ore body targets are identified based on mineral exploration indicators, and drilling is conducted to verify the ore body targets.

[0090] The method for identifying porphyry copper-molybdenum deposits provided by this invention determines the prospecting direction from three levels: regional geological understanding, metallogenic theory, and metallogenic model, ensuring the accuracy of the prospecting direction. Furthermore, by combining the prospecting direction and metallogenic potential, target areas suspected of containing porphyry copper-molybdenum deposits are screened, and the distribution of various geological bodies in the target areas is depicted using multiple small-scale methods. The spatial distribution of concealed intrusive bodies and related metallogenic geological bodies is predicted, thereby determining the metallogenic region and ensuring its accuracy and reliability. Utilizing the spatial zoning theory model of porphyry deposits, the spatial metallogenic theory model of skarn deposits, and the three-layer electrical structure characteristics of electrical sounding, prospecting indicators are identified from the metallogenic region, ensuring the accuracy of the prospecting indicators. Based on this, drilling is used to verify whether the ore bodies corresponding to the prospecting indicators in the metallogenic region are potential mineralization targets for porphyry copper-molybdenum deposits, improving the accuracy and reliability of the determination results.

[0091] It should be noted that the steps shown in the above process or in the flowchart of the accompanying figures can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flowchart, in some cases the steps shown or described may be executed in a different order than that shown here.
