 The main ore body of Mashan gold-copper-sulphur deposit in Tongling, Anhui Province is in stratiform occurring between the dolomite and limestone of the Middle Carboniferous Huanglong Formation. Ore textures and structures, stratigraphical zoning of ore-forming elements, trace element geochemistry of sulphide minerals, and sulphur and lead isotopes indicate that it is a Carboniferous Sedex massive sulphide deposit that was exposed to reworking and overprinting of Yanshanian quartz diorite intrusion. A number of sulphide deposits are similar genetically to the deposit in the lower Yangtze fault depression zone.
