矿床产于叠加在中生代褶皱带之上的火山拗陷内白垩纪火山穹窿建造中。围岩由早白垩世层状酸性火山岩和超覆其上的陆源含煤岩层所组成。在深部,火山岩中有未出露地表的晚白垩世花岗岩类岩体侵入。矿体局限在具不同方向的脉带和矿脉范围内。对于金、银来说,产于近南北向构造中的热液阶段早期 The deposit was produced in Cretaceous volcanic domes built in a volcanic depression superimposed over the Mesozoic fold belt. Surrounding rocks are composed of Early Cretaceous layered acidic volcanic rocks and overlying terrigenous coal-bearing formations. In the depths, Late Cretaceous granitic intrusions in the volcanic rocks have not been exposed. Ore confined in different directions of the vein and vein range. For gold, silver, produced in the near north-south tectonic hydrothermal phase early
