广西世加金矿地质特征浅析

Analysis of Geological Characteristics of Shijia Gold Mine in Guangxi

世加位于华南板块,南华活动带,右江褶皱系,百色凹陷龙川背斜核部及北东翼。世加金矿主要产于二叠纪辉绿岩与石炭系下统鹿寨组接触带附近,受层间构造或地质构造线控制,围岩蚀变以硅化及黄铁矿化与金矿化最为密切。

Shijia is located in the South China Plate,the South China Active Belt,the Youjiang Fold System,the core and northeast wing of the Longchuan Anticline in the Baise Depression.The Shijia gold deposit mainly occurs near the contact zone between the Permian diabase and the Lower Carboniferous Luzhai Formation.It is controlled by interlayer structures or geological structural lines,and the surrounding rock alteration is most closely related to silicification,pyrite mineralization,and gold mineralization.
