| 摘 要： | 卡务地区处于卡务倒转背斜中段,金矿严格受该背斜近轴断层破碎蚀变带控制,矿体呈似层状、透镜状沿断层破碎蚀变带分布。上二叠统领薅组Au、As、Sb、Hg高背景值可能与岩石中含玄武质有关,为金矿提供物质来源,附近偏碱性超基性岩体可能为含矿热液运移富集提供热能,主要属低温热液矿床。

| Abstract: | In the Kawu area,located at middle segment of Kawu reverse anticline,the gold deposit is severely dominated by fracture altered zone near the axis of the anticline,ore bodies,stratoid and lenticular in form,distribute along fracture altered zone.High setting values of Au,As,Sb and Hg in the Upper Permian Linghao Formation are probably correlated with the basalt in the rocks,these elements supply the gold deposit with source,whereas neighboring alkalescent ultramafic rocks probably provide heat energy for migration and concentration of ore-bearing hydrothermal fluids,it mostly belongs to epithermal deposit. |
