H2S和SO2气体地球化学测量在云南普朗斑岩铜矿中的应用
Application of H2S and SO2 gas geochemical measurements in the Pulang porphyry copper deposit,Yunnan Province
摘要
Abstract
Given the difficulty in identifying and extracting exploration information in covered areas,the search for porphyry copper deposits faces significant challenges.[Objective]The ore bodies in porphyry copper deposits are primarily low-grade metal sulfides,and further research is needed to determine the depth and extent of these deposits via gas geochemistry.[Methods]Preliminary experiments were conducted in this study using a portable gas analyzer for H2S and SO2 geochemical measurements at the Pulang porphyry copper deposit.[Results]The results indicate significant H2S and SO2 geochemical anomalies above copper mineralization,suggesting the method's efficacy in revealing hidden ore bodies and predicting their strike and dip extensions.[Conclusion]Areas showing good synergistic behavior,continuous anomalous concentration distributions,and potential for mineralization are promising targets for exploration.This approach represents an effective method for mineral exploration in covered porphyry copper deposits,offering new insights into prospecting concealed mineral resources.关键词
