摘要
溪灯坪金矿矿体赋存于新近系上新统三营组二段(N_2s^2)和第四系更新统(Qp)岩层中,矿体稳定,呈似层状展布。受后期深部岩浆岩热液影响,元古界变质岩系中的金物质被活化形成含金热液,并一定的构造运移至地表析出沉淀,形成金矿床。
The ore body of Xidengping Au deposit is in Neogene Pliocene Sanying Formation Member 2 （N2s2） and Quartemary Pleistocene （Qp） rock beds. The ore body is stratoid, stable. Because of the influence of the late deep magmatic thermal fluid, the activation of Au material in Proterozoie metamorphic rock series forms Au-bearing thermal fluid, migrates to the surface along a certain structure, precipitates and forms the Au deposit.
