摘要
大庙山金矿赋存于倒转背斜东翼、次级紧闭倒转背斜核部及两翼,受灯影组中段层间破碎带及北东向构造破碎带控制。以自然金为主,银金矿次之。三种赋存状态:独立自然金、包体金和超分散金。地球化学Au异常与含金地层吻合,矿石与围岩有继承关系。
Damiaoshan Au deposit is in the core and 2 limbs of secondary close reversed anticline on the E limb of the reversed anticline, controlled by the interbedded fracture zone of Dengying Formation and the NE struc- tural fracture zone. The major ore is native glod, the minor is electrum. And the occurrence state includes independent native gold, inclusion Au and ultra - scattered Au 3 types. The Au geochemical anomaly is in harmony with the Au -bearing bed. And there is the heritage relationship between ore and wall rock.
