DETAILED DESCRIPTION

[0021] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application.

[0022] First, let’s explain the terms involved in this application: The cerium anomaly value (δCe) is an indicator used to assess the degree of Ce anomaly in rare earth element geochemistry.

[0023] Europium anomaly (δEu) is an indicator used to assess the degree of Eu anomaly in rare earth element geochemistry.

[0024] The mineral exploration method based on mineralization potential provided in the present application extracts characteristic information of multiple zircon samples and determines whether the characteristic information of multiple zircon samples meets at least two of the target conditions. If it is determined that at least two of the target conditions are met, the mineralization potential of the target area is determined to be greater than or equal to a preset level, and mineral exploration is carried out on the target area.

[0025] The following specific embodiments describe in detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0026] Figure 1Schematic diagram of the mineral exploration method based on mineralization potential provided for this application Figure 1 , the method of this embodiment includes: S101. Acquire multiple zircon samples in a target area.

[0027] Specifically, zircon samples are first collected, for example, zircon samples are collected from different locations, and the mineralization potential of the target area is determined by analyzing the zircon samples.

[0028] Optionally, the zircon sample is collected from a drill core, the lithology of which is diorite, mainly including plagioclase, potassium feldspar, biotite, hornblende, quartz, etc., for example, the SiO2 content is 53% to 62%.

[0029] S102, extracting characteristic information of the plurality of zircon samples, and determining whether the characteristic information of the plurality of zircon samples meets at least two of target conditions; wherein the characteristic information includes at least two of the following: trace element content, abnormal value of target element, or oxygen fugacity; Specifically, characteristic information of each zircon sample is extracted, such as the trace element content, abnormal value of target elements and oxygen fugacity of the zircon sample; Since the characteristic information of zircon samples in target areas with different mineralization potentials manifests differently, the mineralization potential of the target area where the zircon samples are located can be determined based on the manifestation of different characteristic information.

[0030] Determine whether each characteristic information meets the corresponding requirements in the target conditions, for example, whether the degree of dispersion of the trace element content is greater than or equal to the preset degree; whether the range of variation of the abnormal value of the target element is greater than or equal to the preset range; whether the number of zircon samples with oxygen fugacity greater than or equal to the preset threshold is greater than or equal to the preset number.

[0031] Optionally, the target elements may include cerium, and / or europium.

[0032] S103. If it is determined that at least two of the target conditions are met, determine that the mineralization potential of the target area is greater than or equal to a preset level, and conduct mineral exploration in the target area.

[0033] Specifically, based on the determination result of S102, if it is determined that at least two of the target conditions are met, the mineralization potential of the target area is determined to be high, for example, greater than or equal to a preset level, and mineral exploration is performed on the target area.

[0034] Optionally, if at least two of the target conditions are met, it means that the target area has a better mineralization potential, for example, the level of mineralization potential is higher, greater than or equal to a preset level.

[0035] Alternatively, if all the target conditions are met, it means that the target area has a relatively good mineralization potential, for example, the mineralization potential level belongs to the first level range; If any two of the target conditions are met, it means that the target area has good mineralization potential, for example, the mineralization potential level belongs to the second level range. The level of the first level range is greater than the level of the second level range.

[0036] For example, if at least two of the target conditions are met, such as the number of zircon samples with oxygen fugacity greater than or equal to a preset threshold is greater than or equal to a preset number, then the larger the number of zircon samples, the higher the level of mineralization potential; if the degree of dispersion of the trace element content is greater, the higher the level of mineralization potential; if the range of variation of the outlier value of the target element is larger, the higher the level of mineralization potential.

[0037] Alternatively, the greater the dispersion of the trace element content, the greater the mineralization potential, for example, the higher the grade of mineralization potential.

[0038] Optionally, the larger the variation range of the abnormal value of the target element is, the greater the mineralization potential is, for example, the higher the grade of the mineralization potential is.

[0039] Optionally, the greater the number of zircon samples having an oxygen fugacity greater than or equal to a preset threshold, the greater the mineralization potential, for example, the higher the grade of mineralization potential.

[0040] The mineral exploration method based on mineralization potential provided in an embodiment of the present application obtains multiple zircon samples in a target area; extracts characteristic information of the multiple zircon samples, and determines whether the characteristic information of the multiple zircon samples meets at least two of target conditions; wherein the characteristic information includes at least two of the following: trace element content, abnormal value of target element, or oxygen fugacity; if it is determined that at least two of the target conditions are met, the mineralization potential of the target area is determined to be greater than or equal to a preset level, and mineral exploration is performed on the target area; wherein the target conditions include at least two of the following: the dispersion degree of trace element content is greater than or equal to a preset degree; the variation range of abnormal value of target element is greater than or equal to a preset range; the number of zircon samples with oxygen fugacity greater than or equal to a preset threshold is greater than or equal to a preset number, wherein the trace element content includes the content of at least one of light rare earth elements, rare earth elements, and heavy rare earth elements. In the above embodiment, the mineralization potential of the target area is determined based on the performance of the characteristic information of the zircon samples, that is, whether the target conditions are met, and the determination result is more accurate, thereby making the mineral exploration more efficient, avoiding unnecessary waste of manpower and material resources, and reducing costs.

[0041] Optionally, the target condition also includes: The ratio of the isotope content is greater than or equal to a first preset value; Determining whether the characteristic information of the plurality of zircon samples meets at least two of the target conditions includes: determining whether characteristic information of the plurality of zircon samples satisfies at least two of the target conditions, and determining whether a ratio of isotope contents is greater than or equal to a first preset value; If it is determined that at least two of the target conditions are met, determining that the mineralization potential of the target area is greater than or equal to a preset level, and conducting mineral exploration in the target area, including: If it is determined that at least two of the target conditions are met, and if it is determined that the ratio of the isotope content is greater than or equal to a first preset value, then the mineralization potential of the target area is determined to be greater than or equal to a preset level, and mineral exploration is carried out on the target area.

[0042] Specifically, the target condition also includes: the ratio of the isotope content is greater than or equal to a first preset value; Optionally, a ratio analysis of the isotope content is performed based on the hafnium Hf element. Hafnium has six natural stable isotopes: hafnium 174, 176, 177, 178, 179, and 180.

[0043] The ratio of isotope content includes, for example, at least one of the following: 176 Hf content / 177 Hf content, 176 Lu content / 177 Hf content, 176 Yb content / 177 Hf content, 170 Yb content / 175 Hf content, 179 Hf content / 177 Hf content.

[0044] 176 Lu and 176 Yb is an isotope of Lu.

[0045] 174 Hf is a radioactive isotope that decays to form stable 170 Yb. 176 Lu is a radioactive isotope that decays to form stable 176 Hf.

[0046] If it is determined that at least two of the target conditions are met, and if it is determined that the ratio of the isotope content is greater than or equal to the first preset value, it means that the mineralization potential of the target area is large, that is, it is determined that the mineralization potential of the target area is greater than or equal to the preset level, and mineral exploration is carried out in the target area.

[0047] In the above embodiment, by further adding the limitation of the target conditions, that is, on the basis of satisfying at least two of the above target conditions, further determining whether the ratio of the isotope content is greater than or equal to the first preset value, the accuracy of determining the mineralization potential is further improved.

[0048] Optionally, in step S102, “determining whether the characteristic information of the plurality of zircon samples satisfies at least two of the target conditions” can be specifically implemented as follows: In the case where the trace element content includes the content of heavy rare earth elements, if the discrete degree of the content of the heavy rare earth elements is greater than or equal to a preset degree, it is determined that the discrete degree of the trace element content in the target condition is greater than or equal to the preset degree.

[0049] Specifically, experimental studies have found that the degree of dispersion of heavy rare earth elements is more significant than that of light rare earth elements. Therefore, when the trace element content includes the content of heavy rare earth elements, only the degree of dispersion of heavy rare earth elements can be considered. If the degree of dispersion of the heavy rare earth element content is greater than or equal to the preset degree, that is, only the degree of dispersion of the heavy rare earth element content meets the target condition of being greater than or equal to the preset degree, then it can be determined that the degree of dispersion of the trace element content that meets the target condition is greater than or equal to the preset degree.

[0050] In the above embodiment, when the trace element content includes the content of heavy rare earth elements, if the discrete degree of the content of the heavy rare earth elements is greater than or equal to a preset degree, it is determined that the discrete degree of the trace element content in the target condition is greater than or equal to the preset degree. Since only the discrete degree of the content of heavy rare earth elements is considered, the efficiency of mineral exploration is higher and the accuracy is not affected.

[0051] Optionally, determining whether the characteristic information of the plurality of zircon samples meets at least two of the target conditions includes: Calculating the standard deviation of the variation of the trace element content; If the standard deviation is greater than or equal to a second preset value, it is determined that the dispersion degree of the trace element content is greater than or equal to a preset degree.

[0052] Specifically, in order to improve the accuracy of the calculation, the dispersion of the trace element content can be described based on the standard deviation (σ). First, the standard deviation of the variation range of the trace element content is calculated; If the standard deviation is greater than or equal to the second preset value, it is determined that the dispersion degree of the trace element content is greater than or equal to the preset degree.

[0053] For example, the Lu element content of diorite in area 1 (Lu) N is 1365.43×10 -6~9521.52×10 -6 , the change range is 8156.09×10 -6 , the standard deviation is 71.78×10 -6 ; Lu element content of diorite in area 2 (Lu) N is 1587.35×10 -6 ~8915.66×10 -6 , the change range is 7328.31×10 -6 , the standard deviation is 55.66×10 -6 ; Region 3 diorite (Lu) N is 2451.76×10 -6 ~7882.21×10 -6 , the change range is 5430.45×10 -6 , the standard deviation is 41.90×10 -6 , indicating that the mineralization potential of area 1 is relatively large.

[0054] For example, the standard deviation of the variation of rare earth element contents in multiple regions (regions 1-4) (×10 -6 ) were 7974.40, 6755.18, 5327.09, and 3028.13 respectively; the standard deviation of the variation range of heavy rare earth element content (×10 -6 ) were 7748.62, 6612.60, 5107.45, and 2959.75 respectively; the standard deviation of the variation range of light rare earth element content (×10 -6 ) are 230.16, 144.91, 228.00, and 129.80, respectively, indicating that the mineralization potential of area 1 is relatively large.

[0055] In the above embodiment, by calculating the standard deviation of the variation range of the trace element content, it is determined based on the standard deviation whether the dispersion degree of the trace element content is greater than or equal to the preset degree, and the result is more accurate.

[0056] Optionally, there are significant differences in the dispersion of the light rare earth element (LREE) content, heavy rare earth element (HREE) content, and rare earth element (REE) values ​​of zircon samples with different mineralization potentials. Therefore, the mineralization potential of the target area can be determined based on the dispersion of the original values ​​of the light rare earth element (LREE) content, heavy rare earth element (HREE) content, and rare earth element (REE) content. The greater the variation in the LREE, HREE, and REE contents, the stronger the mineralization potential; the smaller the variation in the LREE, HREE, and REE contents, the smaller the mineralization potential. Optionally, the outliers of the target element include: cerium outliers; and / or, Determining whether the characteristic information of the plurality of zircon samples meets at least two of the target conditions includes: As the temperature decreases, if the variation ranges of the cerium anomaly value and the europium anomaly value of the zircon sample are both greater than or equal to the preset ranges, it is determined that the variation range of the anomaly value of the target element meeting the target condition is greater than or equal to the preset range.

[0057] Specifically, the mineralization potential of the target area can be determined based on the variation range of the cerium anomaly values ​​of zircon samples. For example, although the cerium anomaly values ​​δCe of zircon samples in target areas with different mineralization potentials are all positive anomalies, there are still obvious differences. The cerium anomaly value δCe of zircon samples in target areas with better mineralization potential has a larger variation range. Therefore, when the variation range of the cerium anomaly value δCe is greater than or equal to the preset range, it can be determined that the mineralization potential of the target area is greater.

[0058] Optionally, during the geological evolution process, as the temperature decreases, the δCe and europium anomaly values ​​δEu of zircons in different regions show certain differences. For example, for zircons in target areas with good mineralization potential, as the temperature decreases, both δCe and δEu undergo more significant changes, that is, the range of variation is large, while for zircons in target areas with low mineralization potential, no obvious regular changes are found in δCe and δEu, and the range of variation is extremely small. Therefore, if the range of variation of the cerium anomaly value and the europium anomaly value of the zircon sample is greater than or equal to the preset range, it is determined that the range of variation of the anomaly value of the target element that meets the target condition is greater than or equal to the preset range, which means that the mineralization potential of the target area is greater.

[0059] In the above embodiment, based on the cerium anomaly value, or the variation range of the cerium anomaly value and the europium anomaly value, it can be determined whether the variation range of the anomaly value of the target element in the target condition is greater than or equal to the preset range, and then determine whether the mineralization potential of the target area is greater than or equal to the preset level, thereby determining whether to conduct mineral exploration, so that the accuracy of mineral exploration is higher, avoiding unnecessary waste of manpower and material resources, and low cost.

[0060] Alternatively, as Figure 2 As shown, the method further includes: S102a, extracting age characteristics of the plurality of zircon samples, and determining the mineral age of the target area based on the extracted age characteristics; The “mineral exploration of the target area” in S103 is specifically implemented by: Conduct mineral exploration in the target area based on the mineral age of the target area.

[0061] Optionally, it should be noted that S102a and S102 are performed in no particular order.

[0062] Alternatively, the age of the zircon sample can be determined based on its morphological characteristics, such as the mineral age of the target area.

[0063] For example, in mineral deposits dating back to the Mesozoic and Archean-Proterozoic eras, Mesozoic zircons are mostly columnar, with grain sizes ranging from 50 to 200 μm and a major-to-minor axis ratio of 2:1 to 5:1. These zircons vary widely in grain size and major-to-minor axis ratio. They are highly euhedral, with distinct rhythmic zoning. Archean-Proterozoic zircons are mostly short columnar, with grain sizes ranging from 50 to 100 μm and a major-to-minor axis ratio of 2:1 to 3:1. These zircons vary less in grain size and major-to-minor axis than Mesozoic zircons. They are highly euhedral, with distinct rhythmic zoning, and some zircons have accretionary rims.

[0064] Optionally, the ages of multiple zircon samples in the target area are weighted averaged to obtain the mineral age of the target area.

[0065] In the above implementation, by determining the age of the mineral and then conducting mineral exploration in the target area, different scenario requirements can be met.

[0066] Optionally, in step S102, “determining whether the characteristic information of the plurality of zircon samples satisfies at least two of the target conditions” can be implemented as follows: For any of the zircon samples, determining the oxygen fugacity of the zircon sample based on the cerium anomaly value in the zircon sample and the absolute temperature of zircon crystallization; According to the oxygen fugacity of the plurality of zircon samples, it is determined whether the number of zircon samples having an oxygen fugacity greater than or equal to a preset threshold is greater than or equal to a preset number.

[0067] Specifically, first, the oxygen fugacity of each zircon sample in the plurality of zircon samples is determined respectively, for example, the oxygen fugacity of each zircon sample is determined based on the cerium anomaly value and the zircon crystallization temperature of each zircon sample; According to the oxygen fugacity of each zircon sample, the number of zircon samples with oxygen fugacity greater than or equal to a preset threshold is determined. If the number of zircon samples is greater than or equal to the preset number, it is determined that the third condition in the target condition is met, namely, "the number of zircon samples with oxygen fugacity greater than or equal to the preset threshold is greater than or equal to the preset number", that is, the more zircon samples with oxygen fugacity greater than or equal to the preset threshold, the greater the mineralization potential.

[0068] In some embodiments, “determining the oxygen fugacity of the zircon sample based on the cerium anomaly value in the zircon sample and the zircon crystallization temperature” can be achieved as follows: The oxygen fugacity of the zircon sample is determined according to the following formula: Ln(Ce / Ce*) D=(0.1156±0.0050)*Ln(fO2)+(13860±708) / T-(6.125±0.484); Where, (Ce / Ce*) D refers to the Ce anomaly value in the zircon sample, fO2 represents oxygen fugacity, and T represents the zircon crystallization temperature; Wherein, the T is determined according to the following formula: T=(4800±86) / ((5.711±0.072)-lg(Ti))-273.15; Here, Ti represents the content of titanium element.

[0069] Specifically, the zircon titanium Ti geological thermometer formula is: lg(Ti)=(5.711±0.072)-(4800±86) / T -logαSiO2+ logαTiO2.

[0070] For the system where zircon and rutile coexist, it is usually assumed that αTiO2=1. If it is assumed that αSiO2=1, the zircon crystallization temperature is: T=(4800±86) / ((5.711±0.072)-lg(Ti))-273.15.

[0071] Wherein, Ti represents the content of titanium element Ti, and the unit is °C. Based on the calculation of the zircon Ti thermometer and combined with the zircon Ce anomaly value, the oxygen fugacity of the zircon sample is determined according to the following formula (1): Ln(Ce / Ce*) D =(0.1156±0.0050)*Ln(fO2)+(13860±708) / T-(6.125±0.484); Where, (Ce / Ce*) D refers to the abnormal value of cerium Ce in the zircon sample, fO2 represents the oxygen fugacity, and T represents the zircon crystallization temperature.
