溆浦南江坪金矿地质特征及成因认识

摘要

Nanjiangping gold deposit is located in Xintianxiang,Qiaojiang Town,Xupu County,Hunan Province,which is in the core part of Taojinping gold field.After geological prospecting up to 12 years,geological prospecting has achieved for a breakthrough in recent years.The deposit type is belonged to alteration type gold deposit of cleavage zone,with the characteristics of extensive cleavage (schistosity) development,wide range of alteration and strong alteration degree,many orebodies.It is the important prospecting target area to realize gold prospecting breakthrough in Taojinping gold field.Based on the research of deposit prospecting,it is summarized for the geological features,metallogenic regularity,ore-controlling factors and enrichment regularity of the deposit.It can be referred for the exploration of the similar gold deposit in the area.%南江坪金矿位于湖南省溆浦县桥江镇新田乡,处于陶金坪金矿田的核心部位.经过长达12年的地质勘查,近几年地质找矿有所突破.矿床类型属劈理带蚀变型金矿床,具劈理(片理)发育程度广、蚀变范围大、蚀变程度强、矿体数量多等特点,是陶金坪金矿田实现金矿找矿突破希望所在.经对该矿床勘查研究,总结出该矿床的地质特征、成矿规律、控矿因数及富集规律等,为本区寻找类似之金矿床提供参考.
