摘　　要：南盘江-右江成矿区是我国第21个重要的成矿区带,广西的乐业县大坝地区便处于该成矿区带上。笔者通过对典型矿床地质特征的研究,认为乐业县大坝地区赋矿岩性分布广泛,背斜构造及其断裂组合发育,围岩蚀变强烈,深部找矿空间巨大,找矿前景十分乐观。The Nanpanjiang Youjiang metallogenic zone is the 21st important metallogenic zone in China,and the dam area of Leye County in Guangxi is located in this metallogenic zone.Based on the study of the geological characteristics of typical deposits,the author thinks that the ore hosting lithology in the dam area of Leye County is widely distributed,the anticline structure and its fault combination are developed,the wall rock alteration is strong,the deep exploration space is huge,and the exploration prospect is very optimistic.
