摘要
含金岩石为上二叠统沉凝灰岩。矿体产状与岩层产状基本一致,黄铁矿—毒砂—石英组合含金较好。矿床成因包括火山喷发和热液改造二个阶段。
The Au-bearing bed is the Upper P tuffite.The occurrence of ore body is basically concordant with that of the rock bed.The Au-bearing capacity of pyrite-arsenopyrite-quartz assemblage is somewhat better.The genesis includes 2 stages of volcanic eruption and hydrothermal reformation.
