摘要
桂西某中性岩体裂隙蚀变微细粒型金矿床，是在桂西地区新近发现的一种新类型金矿，金矿体主要产于石英闪长岩体的减压扩容部位的张剪性裂隙中。金的成矿物质来源与石英闪长岩有关。构造应力场多期次作用是促使金再次活化迁移富集成矿的主要动力机制。
Fissure-altered microfine type gold deposit of certain intermediate rockkanew typeof gold deposit found recently in Western Guangxi． Gold ore principally lies in the tenso-shear fissure of depressured-enlarged capacity position of quartz diorite. Gold soures arerelated to the activity of quartz diorite. Polyphrase structural stress field is the maindynamic mechanisni to make gold reactivate and transport and enrich to for ore.
