Geological conditions of copper deposits associated with the Emeishan basalt in the Panxian area, Guizhou

Take for example the Huangjiankeng-Hashu rich copper belt occurring on the contact surface between the base of the Emeishan basalt and limestone of the Middle Permian Maokou Formation, the paper discusses the geological conditions of this new type of basalt copper deposit and the effects of the eruption of the Emeishan basaltic magma on the concentration of elemental Cu (Au, Pb, Zn, Pt, Pd, Sb, Fe etc.) and modification of mineralization by late-stage hydrothermal fluids.
