摘要
铜银矿产于上三叠统小定西组玄武岩、安山玄武岩、安山玄武质凝灰角砾岩的构造破碎带中,局部为破碎带旁侧蚀变带、蚀变发育的方解石脉中。品位均较稳定。已发现矿化体5条。矿床成因为与火山岩有关的中温热液型铜银矿床。
The Cu -Ag deposit exists in the fracture zone of Upper Triassic Xiaodingxi Formation basalt, andesitic basalt and andesitic basalt tuff aceous breccia, locally in the altered calcite vein of the alteration zone beside the fracture zone. The grade is stable. We have found 5 metalloge- netic bodies. The genesis of ore deposit belongs to the middle T hydrothermal type Cu -Ag deposit in relation to the volcanic rock.
