简论湖北兴山罗家埫黄铁矿矿床成因及找矿

GENESIS AND PROSPECTING OF LUOJIACHONG PYRITE DEPOSIT IN XINGSHAN

罗家十尚黄铁矿矿床主要赋存在震旦系陡山沱组樟树坪段的断裂和溶洞中。是加里东运动初期和末期成矿作用的产物。矿床是在地表水和裂隙水的作用下，溶蚀矿源层中的部分矿物和元素，在还原环境中，次生富集于断裂和溶洞中而成。

As a stratabound deposit,hosted in the faults and karst caves in Zhangshupin Member,Doushantuo Formation,Sinian System,Luojiachong pyrite deposit is the result of the mineralization in the primary stage and final stage of Caledonian origeny.In the process of the mineralization,the metallogenic minerals and elements in the source bed were partly dissolved by surface water and fissure water and then hosted in the faults and karst caves by secondary enrichment in reductive environment.
