摘要
白马洞铀汞钼多金属矿床位于黔北隆起区之凤冈南北向隔槽式褶皱变形区西南部部断裂构造与热点复合部位。东西向白马洞深大断裂带控制黔中地区热液铀多金属矿分布。白马洞断裂上盘发育多层次层间构造滑脱体系。铀多金属矿带分布在北东向犀牛洞断裂与东西向白马洞断裂斜接复合部位。铀汞钼矿体赋存于寒武系高台组页岩上下盘层间构造破碎带中。矿床内热液活动明显,蚀变强烈,蚀变种类多,以硅化、黑色蚀变为主,矿物成分复杂。预测深部震旦系灯影组底部与顶部及南沱组与清水江组之间发育层间构造破碎带,可能有铀、汞、钼多金属矿体赋存与富集。
Baimadong urauium,mercury and molybdenum polymetallic deposit located in the southwest fracture and hotspot composite position of SN through-like folded deformation area in Fenggang of north Guizhou uplift area EW Baimadong deep and big fracture belt controls hydrothermal urauium polymetallic deposit distribution of central Guizhou Multi-level interlayer structural detachment system develop on the Baimadong fracture Urauium polymetallic belt distribute in the scarf composite position of NE Xiniudong fracture and EW Baimadong fracture Urauium,mercury and molybdenum orebody occur in the structural fracture zone between the up and down layer of Gaotai formation shale rock in Cambrian system The hydrothermal activity in the deposit is obvious,the alteration is strong and has different types,mainly are silication and black alteration,the component of ore is complex There maybe the occurrence and concentration of urauium,mercury and molybdenum in the interlayer fracture zone of upper and lower Dengying formation and between Nantuo formation and Qingshuijiang formation.
