【Abstract】 The Sandaoya mining area is located in the Kangxi axis(II-level tectonic unit) and the Luding-Miyitai arch(III-level tectonic unit) in the eastern part of the Panxi rift in the southwestern margin of the Yangtze platform(I-level tectonic unit). Middle section of Taichung(Class IV structural unit). The copper ore body is mainly produced in the contact zone between the basalt and the Yangxin Formation limestone of the Permian Jurassic, the basaltic fracture zone and the contact zone between the Emeishan basalt and the Triassic sandstone shale.
