Description

Technical Field

[0001] The embodiments of this application relate to the field of geophysics, and in particular to a method and system for determining favorable mineralization sites within fault uplift zones. Background Technology

[0002] The statements herein are provided merely as background information in connection with this application and do not necessarily constitute prior art.

[0003] In sedimentary basins, fault-uplift zones formed by large faults cutting through uplifted areas are closely related to the mineralization of regional sandstone-type uranium deposits. In the early stages of mineralization, the fault-uplift zone, along with the paleo-uplift background of the sedimentary period, controls the spatial distribution of favorable sand bodies such as braided rivers and deltas. During the mineralization period, the fault-uplift zone restricts the size and distribution range of uranium source bodies, controls the groundwater recharge-drainage system, interlayer oxidation, and the development of sedimentary facies zones. Its associated faults provide advantageous channels and mineralization supplies for the migration of uranium-bearing and oxygen-rich fluids. In the later stages of mineralization, the continuous uplift and fault activity of the fault-uplift zone further provide channels for the upward migration of ore-forming fluids from the basin margins and deeper layers. Therefore, the controlling role of fault-uplift zones in uranium mineralization should be considered in regional mineral exploration. Summary of the Invention

[0004] A brief overview of this application is provided below to offer a basic understanding of certain aspects thereof. It should be understood that this overview is not an exhaustive summary of the application. It is not intended to identify key or essential parts of the application, nor is it intended to limit its scope. Its purpose is merely to present certain concepts in a simplified form as a prelude to the more detailed description that follows.

[0005] One aspect of this application provides a method for determining favorable mineralization sites within a fault-uplift zone, comprising the following steps: S10: determining the distribution of fault-uplift zones within a target area; S20: determining the distribution of uranium-rich rock bodies controlled by the fault-uplift zone; S30: determining favorable mineralization strata based on the uranium-rich rock bodies; S40: determining the post-alteration alteration zoning of sand bodies within the favorable mineralization strata; S50: determining favorable mineralization sites within the fault-uplift zone based on the post-alteration alteration zoning.

[0006] The method for determining favorable mineralization sites within fault-uplift zones provided in this application first identifies the distribution of fault-uplift zones, then determines the uranium-rich rock bodies controlled by them, thereby obtaining favorable mineralization strata. Furthermore, it analyzes the epigenetic alteration zoning of sand bodies within these favorable strata, gradually limiting the exploration area to determine specific favorable mineralization sites. This allows the exploration target to be gradually narrowed from a large area to a local sand body, effectively improving spatial positioning accuracy, reducing ineffective drilling, and enhancing the targeted nature of engineering deployment.

[0007] This application, in another aspect, provides a system for determining favorable mineralization sites within a fault-uplift zone, comprising: a fault-uplift zone determination module for determining the distribution of fault-uplift zones within a target area; a uranium-rich rock mass determination module for determining the distribution of uranium-rich rock masses controlled by the fault-uplift zone; a favorable mineralization stratum determination module configured to determine favorable mineralization strata based on the uranium-rich rock masses; an epigenetic alteration zoning determination module for determining the epigenetic alteration zoning of sand bodies within the favorable mineralization strata; and a favorable mineralization site determination module configured to determine favorable mineralization sites within the fault-uplift zone based on the epigenetic alteration zoning.

[0008] The system provided in this application for determining favorable mineralization sites within fault-uplift zones first identifies the distribution of the fault-uplift zone, then determines the uranium-rich rock bodies controlled by it, thereby obtaining favorable mineralization strata. It then analyzes the epigenetic alteration zoning of sand bodies within these favorable strata, gradually limiting the exploration area to pinpoint specific favorable mineralization sites. This allows the exploration target to be gradually narrowed from a large area to a local sand body, effectively improving spatial positioning accuracy, reducing ineffective drilling, and enhancing the targeted nature of engineering deployment.

[0013] The following disclosure provides several different implementations or examples for carrying out this application. To simplify the disclosure of this application, specific examples of components and methods are described below. Of course, these are merely examples and are not intended to limit this application. In the description of the embodiments of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0014] Existing methods for determining favorable mineralization areas within a region are mostly focused on the analysis of a single tectonic unit or a local area. This makes it difficult to effectively connect ore-controlling elements at different scales, thus limiting the comprehensiveness and reliability of locating favorable mineralization areas.

[0015] To address the aforementioned problems, one embodiment of this application provides a method for determining favorable mineralization locations within a fault-uplift zone, comprising the following steps: S10: determining the distribution of fault-uplift zones within a target area; S20: determining the distribution of uranium-rich rock bodies controlled by the fault-uplift zone; S30: determining favorable mineralization strata based on the uranium-rich rock bodies; S40: determining the post-alteration alteration zoning of sand bodies within the favorable mineralization strata; S50: determining favorable mineralization locations within the fault-uplift zone based on the post-alteration alteration zoning.

[0016] The method for determining favorable mineralization sites within fault-uplift zones provided in this application first identifies the distribution of fault-uplift zones, then determines the uranium-rich rock bodies controlled by them, thereby obtaining favorable mineralization strata. Furthermore, it analyzes the epigenetic alteration zoning of sand bodies within these favorable strata, gradually limiting the exploration area to determine specific favorable mineralization sites. This allows the exploration target to be gradually narrowed from a large area to a local sand body, effectively improving spatial positioning accuracy, reducing ineffective drilling, and enhancing the targeted nature of engineering deployment.

[0017] In some embodiments, step S30 specifically includes the following steps: S31: identifying sedimentary basins near uranium-rich intrusive bodies; S32: identifying sedimentary formation characteristics within the sedimentary basins; S33: identifying favorable mineralization strata within the sedimentary basins based on the sedimentary formation characteristics.

[0018] After identifying the uranium-rich rock body, the surrounding sedimentary basins are further delineated, narrowing the scope of analysis from the rock body to the interior of the basin. This allows for the analysis of sedimentary formation characteristics within each basin, which not only comprehensively covers potential mineralization areas and avoids omissions, but also eliminates unfavorable strata by identifying sedimentary formation characteristics. This makes subsequent sand body exploration targets more focused and the identification of favorable mineralization strata more targeted, thus improving exploration efficiency while ensuring regional integrity.

[0019] In some embodiments, in step S33, favorable mineralization strata within a sedimentary basin can be determined by identifying strata containing mineralized sand bodies of a certain size that are rich in organic matter or reducing media.

[0020] Specifically, in step S33, sedimentary strata within a sedimentary basin can be considered favorable mineralization horizons if they meet one of the following conditions: a mud-sand-mud structure is developed in the vertical sequence, wherein the sandstone section has the conditions for the main flow channel of groundwater, and the top mudstone forms an impermeable layer, and the bottom mudstone (or coal-bearing mudstone layer) forms an impermeable layer and supplies reducing medium; the intended sedimentary strata themselves are gray and reducing and are capped by the top mudstone; known uranium mineralization has been found in this section; this section belongs to the same sedimentary unit as the aforementioned sections that have been identified as favorable horizons and has consistent sedimentary construction characteristics.

[0021] For example, if the sedimentary strata of a predetermined geological age have thick layers of light yellow and light gray conglomerate, gravelly sandstone, and argillaceous sandstone on the surface, with a coal-bearing mudstone layer at the bottom and a light gray, grayish-green, and purplish-red mudstone layer at the top, the bottom coal-bearing mudstone layer provides an impermeable base and a source of reducing agents, the top mudstone layer forms an impermeable top, and the thick layers of conglomerate, gravelly sandstone, and argillaceous sandstone in the middle serve as the main channels for groundwater flow. Therefore, the middle part of this sedimentary stratum is a favorable stratum for mineralization.

[0022] If, in the vertical sequence of sedimentary strata from a predetermined geological age, the upper part consists of thick layers of purplish-red and grayish-green sandstone and conglomerate, the middle part of purplish-red mudstone, and the lower part of thick layers of gray medium-fine sandstone, then the upper sandstone and conglomerate lacks a protective mudstone cap, and the purplish-red color indicates an oxidizing environment, which is unfavorable for uranium preservation; the middle purplish-red mudstone forms a waterproof cap; and the lower gray medium-fine sandstone itself has reducing properties, serving as a main channel for groundwater flow, and is capped by the middle mudstone layer. Therefore, the lower section of this sedimentary stratum is a favorable ore-forming layer.

[0023] If uranium mineralization has been found in the lower section of a sedimentary stratum in a vertical sequence of a predetermined geological age, it indicates that the lower section has the conditions for uranium enrichment and mineralization. Therefore, the lower section of the sedimentary stratum can be directly identified as a favorable mineralization stratum.

[0024] If sedimentary strata of a predetermined geological age form a unified sedimentary unit within a predetermined basin and possess the same sedimentary formation characteristics, then based on the identified favorable mineralization strata within the same stratigraphic unit of the basin, it can be analogously determined that the same stratigraphic segments within the corresponding stratigraphic unit of the basin are also favorable mineralization strata.

[0025] In some embodiments, step S40 specifically includes the following steps: S41: determining the epigenetic alteration characteristics of sand bodies in favorable ore-forming strata; S42: determining the degree of interlayer oxidation development of sand bodies based on the epigenetic alteration characteristics; S43: determining the oxidation zone, reduction zone, and transition zone developed in sand bodies based on the degree of interlayer oxidation development, so as to obtain epigenetic alteration zoning.

[0026] After identifying favorable mineralization strata, further analysis of the post-alteration characteristics of sand bodies within the strata allows for the determination of the intensity of interlayer oxidation based on the assemblage and distribution of alteration minerals. Consequently, oxidation zones, reduction zones, and transition zones between the two can be delineated within the sand bodies, forming a complete post-alteration zoning sequence. The transition zone, acting as a geochemical barrier, is precisely a favorable location for uranium precipitation and enrichment. This setup provides a direct basis for the subsequent precise location of favorable mineralization sites within the sand bodies.

[0027] In some embodiments, in step S43, the post-alteration alteration zoning can be determined as follows: if the sand body in the favorable mineralization strata within the predetermined area undergoes a transformation between phreatic oxidation and interlayer oxidation from the edge of the uranium-rich rock body toward the interior of the basin, and forms an oxidation zone, reduction zone, and transition zone in sequence along the groundwater flow direction, then the sand body at that location develops large-scale interlayer oxidation, forming a post-alteration alteration zoning.

[0028] For example, if a sand body within a favorable mineralization stratum exhibits a transition from phreatic oxidation to interlayer oxidation from the edge of the uranium-rich rock mass towards the basin interior, with oxidation zones, reduction zones, and transition zones developing sequentially along the groundwater flow direction, then this sand body forms an epigenetic alteration zonation. If a sand body within a favorable mineralization stratum exhibits light yellow, yellow, and grayish-white epigenetic alteration, and a transition from phreatic oxidation to interlayer oxidation from the edge of the uranium-rich rock mass towards the basin interior, with oxidation zones, reduction zones, and transition zones developing sequentially along the groundwater flow direction, then this sand body forms an epigenetic alteration zonation. If a sand body within a favorable mineralization stratum exhibits light yellow and yellow epigenetic alteration, and is jointly controlled by two uranium-rich rock masses, and a transition from phreatic oxidation to interlayer oxidation from the edge of the uranium-rich rock mass towards the basin interior, with oxidation zones, reduction zones, and transition zones developing sequentially along the groundwater flow direction, then this sand body forms an epigenetic alteration zonation.

[0029] In some embodiments, step S20 specifically includes the following steps: S21: determining the radioactive anomaly zone within the target area; S22: determining the distribution of uranium-rich rock bodies controlled by the fault uplift zone based on the distribution of the radioactive anomaly zone and the fault uplift zone.

[0030] By combining the distribution of fault uplift zones and radioactive anomaly areas, radioactive anomaly information within the target area can be comprehensively covered, avoiding omission of rock mass clues related to uranium mineralization. Furthermore, the structural constraints of fault uplift zones can eliminate anomaly interference unrelated to mineralization, making the identification of uranium-rich rock masses more accurate and providing reliable distribution of uranium-rich rock masses for subsequent location of favorable mineralization strata.

[0031] In some embodiments, in step S22, the radioactive anomaly zone and the fault uplift zone can be spatially superimposed to screen out uranium-rich rock bodies controlled by the fault uplift zone. The specific judgment can be determined by those skilled in the art. By superimposing the analysis, the spatial correspondence between the radioactive anomaly and the fault uplift zone can be visually displayed, and the overlapping parts of the two can be quickly identified, thereby more efficiently locating uranium-rich rock bodies controlled by tectonics.

[0032] Figure 1 This is a schematic diagram of the distribution of uranium-rich rock masses determined by the method provided in the embodiments of this application, as shown below. Figure 1 As shown in the figure, the red straight line represents the fault in the target area, the pink block represents granite, the other different colored blocks represent sedimentary strata of different geological ages, the red dashed box indicates the distribution location of uranium-rich rock bodies, the purple curve and striped grid represent the boundary of sedimentary basins, and the blank area enclosed by the boundary of sedimentary basins is the sedimentary basin.

[0033] The uranium-rich rock bodies shown in the figure are mostly distributed in a banded pattern along the periphery of the sedimentary basin and are closely associated with granite bodies. Some of the uranium-rich rock bodies are adjacent to fault zones, indicating that faults act as conduits for the intrusion and emplacement of local uranium-rich rock bodies. Sedimentary strata of different geological ages within the sedimentary basin provide spatial conditions for the migration and accumulation of uranium-bearing fluids. During their migration into the basin, uranium-bearing hydrothermal fluids from the uranium-rich rock bodies are enriched by precipitation in a reducing environment near the contact zone between the rock body and the basin's sedimentary cap. This indicates that the uranium-rich rock bodies identified by the method provided in the embodiments of this application have good systematicity and integrity within the macroscopic region.

[0034] In some embodiments, in step S21, the radioactive anomaly zone includes radioactive uranium, thorium, potassium, and general anomaly zones. By acquiring multi-parameter anomaly information, the enrichment and migration characteristics of different elements can be comprehensively reflected, rather than relying on a single indicator to determine rock mass properties. Spatial overlay analysis of the multi-parameter radioactive anomaly zone and fault uplift zones can intuitively present the spatial matching relationship between radioactive anomalies and structures, effectively eliminating false anomalies caused by non-tectonic factors. Based on this, uranium-rich rock masses controlled by fault uplift zones can be screened out. The specific judgment can be determined by those skilled in the art based on the actual situation.

[0035] Total count anomalies refer to abnormalities in the total count rate across all channels of the gamma spectrum in radiometric measurements. They reflect the overall radioactivity level of the region but do not distinguish between specific elements. Combining total count anomalies with anomalies in uranium, thorium, and potassium can independently identify the inducing factors of radiometric anomalies.

[0036] In some embodiments, in step S21, airborne radioactivity data within the target area can be collected to determine radioactive uranium, thorium, potassium, and total contour maps, and to screen areas with radioactive intensity anomalies, making the distribution of radioactive intensity anomalies more intuitive and facilitating overlay analysis with structural information.

[0037] In some embodiments, in step S10, geological data and uranium mineralization information of the target area can be collected and organized, and the types and spatial distribution characteristics of regional fault zones can be analyzed. If multiple large active fault zones are developed in the region, and a certain main fault zone controls both one boundary of the target basin group and the distribution of uranium-rich rock bodies at the edge of the basin, as well as the distribution of uranium mineralization information around the rock bodies, then this fault zone can be identified as an important basin-controlling, rock-controlling, and ore-controlling fault zone in the region. Furthermore, the spatial distribution of regional uplift zones can be analyzed based on the collected geological data. Characteristics: If multiple large uplifts develop in a region, extending in a northwest-southeast direction, and intersect with the regional main fault zone in the western section, this uplift zone controls both the northern or southern boundary of the target basin group and the distribution of basin marginal rock masses and uranium mineralization information. Based on this, the uplift zone is identified as an important basin-controlling, rock-controlling, and mineralization-controlling uplift zone in the region. According to the aforementioned determination, the regional main fault zone and the regional uplift zone intersect in the western section, and the fault zone cuts the uplift zone, causing it to form a fault-block uplift confined by the fault. Thus, the distribution range of the fault-uplift zone is determined at the intersection.

[0038] Another embodiment of this application provides a system for determining favorable mineralization sites within a fault-uplift zone, comprising: a fault-uplift zone determination module for determining the distribution of fault-uplift zones within a target area; a uranium-rich rock mass determination module for determining the distribution of uranium-rich rock masses controlled by the fault-uplift zone; a favorable mineralization stratum determination module configured to determine favorable mineralization strata based on the uranium-rich rock masses; an epigenetic alteration zoning determination module for determining the epigenetic alteration zoning of sand bodies within the favorable mineralization strata; and a favorable mineralization site determination module configured to determine favorable mineralization sites within the fault-uplift zone based on the epigenetic alteration zoning.

[0039] The system provided in this application for determining favorable mineralization sites within fault-uplift zones first identifies the distribution of the fault-uplift zone, then determines the uranium-rich rock bodies controlled by it, thereby obtaining favorable mineralization strata. It then analyzes the epigenetic alteration zoning of sand bodies within these favorable strata, gradually limiting the exploration area to pinpoint specific favorable mineralization sites. This allows the exploration target to be gradually narrowed from a large area to a local sand body, effectively improving spatial positioning accuracy, reducing ineffective drilling, and enhancing the targeted nature of engineering deployment.

[0040] In some embodiments, the mineralization favorable strata determination module is configured to: determine a sedimentary basin near a uranium-rich intrusive body; determine sedimentary formation characteristics within the sedimentary basin; and determine mineralization favorable strata within the sedimentary basin based on the sedimentary formation characteristics.

[0041] After identifying the uranium-rich rock body, the surrounding sedimentary basins are further delineated, narrowing the scope of analysis from the rock body to the interior of the basin. This allows for the analysis of sedimentary formation characteristics within each basin, which not only comprehensively covers potential mineralization areas and avoids omissions, but also eliminates unfavorable strata by identifying sedimentary formation characteristics. This makes subsequent sand body exploration targets more focused and the identification of favorable mineralization strata more targeted, thus improving exploration efficiency while ensuring regional integrity.

[0042] In some embodiments, the epigenetic alteration zoning determination module is configured to: determine the epigenetic alteration characteristics of sand bodies in favorable mineralization strata; determine the degree of interlayer oxidation development of sand bodies based on the epigenetic alteration characteristics; and determine the oxidation zone, reduction zone, and transition zone developed in sand bodies based on the degree of interlayer oxidation development, so as to obtain epigenetic alteration zoning.

[0043] After identifying favorable mineralization strata, further analysis of the post-alteration characteristics of sand bodies within the strata allows for the determination of the intensity of interlayer oxidation based on the assemblage and distribution of alteration minerals. Consequently, oxidation zones, reduction zones, and transition zones between the two can be delineated within the sand bodies, forming a complete post-alteration zoning sequence. The transition zone, acting as a geochemical barrier, is precisely a favorable location for uranium precipitation and enrichment. This setup provides a direct basis for the subsequent precise location of favorable mineralization sites within the sand bodies.

[0044] In some embodiments, the uranium-rich rock mass determination module is configured to: determine radioactive anomaly zones within a target area; and determine the distribution of uranium-rich rock masses controlled by fault uplift zones based on the distribution of radioactive anomaly zones and fault uplift zones.

[0045] By combining the distribution of fault uplift zones and radioactive anomaly areas, radioactive anomaly information within the target area can be comprehensively covered, avoiding omission of rock mass clues related to uranium mineralization. Furthermore, the structural constraints of fault uplift zones can eliminate anomaly interference unrelated to mineralization, making the identification of uranium-rich rock masses more accurate and providing reliable distribution of uranium-rich rock masses for subsequent location of favorable mineralization strata.

[0046] In some embodiments, the uranium-rich rock mass identification module can perform spatial overlay analysis of radioactive anomaly zones and fault uplift zones to screen out uranium-rich rock masses controlled by fault uplift zones. The specific judgment can be determined by those skilled in the art. By overlay analysis, the spatial correspondence between radioactive anomalies and fault uplift zones is made intuitively apparent, and the overlapping areas of the two can be quickly identified, thereby more efficiently locating uranium-rich rock masses controlled by tectonics.

[0047] In some embodiments, the radioactive anomaly zone includes radioactive uranium, thorium, potassium, and general anomaly zones. By acquiring multi-parameter anomaly information, the enrichment and migration characteristics of different elements can be comprehensively reflected, rather than relying on a single indicator to determine the rock mass properties. Spatial overlay analysis of multi-parameter radioactive anomaly zones and fault uplift zones can intuitively present the spatial matching relationship between radioactive anomalies and structures, effectively eliminating false anomalies caused by non-tectonic factors. Based on this, uranium-rich rock masses controlled by fault uplift zones can be screened out. The specific judgment can be determined by those skilled in the art based on the actual situation.

They reflect the overall radioactivity level of the region but do not distinguish between specific elements. Combining total count anomalies with anomalies in uranium, thorium, and potassium can independently identify the inducing factors of radiometric anomalies.
