| Abstract: | The ore-bearing rock series of Cu deposit in the basalt is a series of ore-bearing volcanic-stratigraphic assemblage with the high Cu background,evident Cu metallogenesis and Cu ore bed in the upper part of Upper P Emeishan Basalt Formation—bottom of Xuanwei Formation,which can be divided into 3 types,ie,1.Cu deposit of basalt type;2.Cu deposit of basalt and C-bearing sedimentary rock interbed type;3.Cu deposit of alminous mudstone on sedimentation gap surface according to the ore-bearing host rock. |
