 Shifengshan copper deposit is one major copper mines in China, which includes two ore blocks of Shishan and Fengshan. Fengshan deposit was occurred outboard of the diapir structure and was a rich type deposit subject to the control of structure post-tectonic superposition. The ore-bearing stratum was the group of the upper part of Luzhijiang Formation, rich ore body of the diapir was surrounded by the fragmental dolomite. Ore occurrence was closely related to the diapir structure morphology, fracture and fissures derived from the structure showed bedded and lenticular occurrences. Volcanic rock vein and breccia within the inner diaper structure occupied a small proportion, mining activities were conducted at the middle plane of the diaper structure.
