Ore prospecting method based on epidote microelements

Abstract

The invention discloses a prospecting method based on epidote microelements. The prospecting method specifically comprises the following steps that a metallogenic section is delineated; sample collection and analysis: collecting a bedrock sample containing epidote from the metallogenic section according to a certain sampling unit; analyzing and testing trace elements; data processing and interpretation: processing the obtained initial record data by using LADRlib software; and discriminating the prospecting action type. The method has the advantages that the LA-ICP-MS in-situ analysis technology is utilized, the description of the epidote altered minerals in the magma-hydrothermal mineralization system is improved from the macroscopic qualitative description to the microcosmic quantitative interpretation of the change of the trace elements, and the change of the trace elements is associated with the response of the scale prospecting type of an ore concentration area; the method overcomes the difficulties of low efficiency, long period and high cost of a traditional prospecting type discrimination method, can provide a theoretical basis for the optimization and selection of a prospecting exploration method for the ore deposit scale, and reduces the exploration risk.

Description

technical field [0001] The invention relates to the technical field of prospecting for geological exploration, in particular to a prospecting method based on epidote trace elements. Background technique [0002] In recent decades, with the comprehensive coverage of geological exploration work, the degree of mineral exploration has gradually improved, and the discovery of new deposits has become more and more difficult. It is urgent to develop new prospecting techniques and methods to guide prospecting breakthroughs. out the prospecting type. [0003] The traditional identification of ore prospecting types has the following shortcomings: before the exploration and evaluation, comprehensive studies such as large-scale mapping and systematic sampling and analysis should be carried out to find out the occurrence of the ore body, the relationship with the surrounding rocks, metallogenic processes, and metallogenic materials. And the source of ore-forming fluids, etc., can determ...

AI Technical Summary

Problems solved by technology

[0003] The traditional identification of prospecting types has the following disadvantages: comprehensive research such as large-scale mapping and systematic sampling analysis must be carried out before exploration and evaluation to find out the occurrence of ore bodies, the relationship with wall rocks, mineralization, and metallogenic materials. The source of ore-forming fluids, etc., can determine the cause of the deposit or the type of ore prospecting, resulting in a long cycle and high costs, which cannot meet the urgent needs of rapid exploration and evaluation at the scale of ore concentration areas
