Abstract
This article takes KD mine as the research object,and based on geological survey,drilling core and geophysical data,systematically analyzes the geological characteristics and prospecting potential of the deposit.Research has shown that KD mine belongs to hydrothermal metal deposits,with ore bodies occurring in the contact zone between sandstone and mudstone shale layers and fracture zones.The main minerals are sphalerite(ZnS)and galena(PbS),accompanied by pyrite(FeS2)and arsenopyrite(As2S3),with Zn grades ranging from 6.8%to 8.5%and Pb grades ranging from 4.3%to 5.9%.The ore body is mainly in the form of veins and lenses,with significant enrichment of Zn in the deep part,and the Zn/Pb ratio gradually increases to 2.8:1.Through stress field inversion and 3D geological model prediction,it is found that the mineralized zone in the fault intersection area and the depth range of 600-850m has strong development and significant prospecting potential.关键词
