摘　　要：通过对粤西某斑岩型钼矿及周边相邻水文地质单元的地表水体、地下水天然露头开展现场pH检测,采用SX836型检测仪查明水体pH异常分布范围。研究阶段系统搜集整理了工作区以往地质工作特征、核实了研究区地层岩性、火成岩出露特征,通过在不同标高、不同地层区域、不同水文地质单元采集土壤样品、岩石样品、泉水、地表水进行检测分析,大致查明了研究区水文地质特征,总结了某斑岩型钼矿周边水体pH变化规律,初步指出了pH异常的成因,有利于进一步查明该区域地下水地球化学特征。By conducting on-site pH testing on the surface water and groundwater natural outcrops of a porphyry type molybdenum mine in western Guangdong and adjacent hydrogeological units,the SX836 detection instrument was used to determine the abnormal distribution range of water pH.During the research phase,the system collected and organized the geological characteristics of the previous work in the study area,verified the lithology of the strata and the exposed characteristics of igneous rocks in the study area.By collecting soil samples,rock samples,spring water,and surface water at different elevations,geological regions,and hydrogeological units for testing and analysis,the hydrogeological characteristics of the study area were roughly identified.The pH change law of the surrounding water body of a certain porphyry type molybdenum mine was summarized,and its genesis was preliminarily analyzed,Beneficial for further identifying the geochemical characteristics of groundwater in the region。
