摘　　要：豫西南地区的二郎坪群西段分布着以银、铅、锌为主的带状异常,通过地质大调查项目实施,对本区进行了地球化学特征研究,重点检查了以银、铅、锌为主的异常。在火神庙组的变石英角斑岩中发现了银、铅、锌多金属矿化带,伴生有金、铜等金属矿化,并对其成因进行了初步分析。区域上存在有众多的以银、铅、锌为主的综合异常和相似的地质环境,区域矿产潜力巨大,随着矿产资源评价工作的全面展开,必然在本区有较大的发现。A series of geochemical Ag-Pb-Zn anomaly belts distribute in the western segment of the Erlangping Group in southwestern Henan Province. During the General-Geological-Investigation, we did a lot of geochemical research work in this area, especially investigated the Ag-Pb-Zn anomalies, and discovered several Ag-Pb-Zn metallogenic belts with Au-Cu metalization in quartz keratophyre of Huoshenmiao Formation. Based on the information from the metallogenic belts, it is seggesed that in this region, there are many Ag-Pb-Zn composite anomalies with almost the same geological environment simiar to the metallogenic belts, and great ore-search potential is in this area also. There will be certainly great discoveries in this area with the exploration work continuing.
