Embodiment 1
[0038] A provenance tracing system using lithological geochemical genes, comprising the following steps:
[0039] S1. Calculate the lithologic geochemical gene pool based on the regional geochemical and multi-target geochemical survey results obtained by previous researchers;
[0040] S2. Collect samples that need to be tested, analyze the necessary element content of the tested samples, and then construct the geochemical gene sequence of the samples;
[0041] S3. Comparing the lithology genes of S2 with the lithology geochemical genes in the S1 gene database, and then calculating the similarity of the genes in the gene pool with respect to the genes in S2;
[0042] S4, outputting the similarity of comparison results;
[0043] S5. Assign a value of 1 to the samples that meet the genetic similarity standard, and assign a value of 0 to samples that do not meet the similarity standard;
[0044] S6. Outputting the assigned data comparison result.
[0045] Further, preferably, t...
Embodiment 2
[0064] Embodiment 2: Based on Embodiment 1, the difference is:
[0065] Collect rock samples, extract the geochemical genes of the rock samples, and determine the element sequence. For details, refer to Table 1 below;
[0066]
[0067] According to the geochemical genes in Table 1 above, bring them into the Earth Gene Database for comparison, and bring the comparison results into the following formula for calculation. For the calculation results, refer to Table 2 below;
[0068]
[0069] For areas where the output comparison result is greater than 80% (or 70%), referring to the above test results, it can be found that the geochemical gene characterizes the characteristics of the relative change trend of the element content of the geological sample. Different geological samples have different geochemical genes, so Geological samples can be identified using geochemical genes. However, due to the complexity of geological processes, the geochemical properties of elements ma...
