通过阐明干沟峡锰矿地质特征，指出该区锰矿主要的控矿因素，为进一步的地质找矿工作提供参考。研究表明：该区锰矿产于震旦系雪花太坪组中岩段的绢云母板岩夹紫色含锰绢云母板岩、含锰灰岩中；中晚元古界郭家沟组细碧岩、凝灰岩含锰丰度高，为初始矿源层；锰呈碳酸盐在海沟-海沟边缘斜坡相对弱的氧化环境下富集，形成锰矿化体。

The study indicates that main ore control conditions by analyzing geological characteristics of Gangouxia Mn ore deposit in order to provide the reference for further geological prospecting work .The results show that Mn ore deposit mainly lies in middle Xuehuataiping Group in Sinian System with purple sericite slate and manganese -bearing limestone .Spilite and tuff with high manganese contents in the Middle-Late Proterozoic Guojiagou group are the initial source bed .Trench-Trench edge slope and slight oxidizing environment result in Mn in form of carbonate enrichment and metallization .
