| Abstract: | 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. |
