Lemachang Ag-(Pb-Zn) deposit, Ludian Co., Zhaotong Prefecture, Yunnan Province, China
Latitude: 27°6'30"N
Longitude: 103°23'0"E
Longitude: 103°23'0"E
Stratiform silver-lead-zinc deposit, occurring in a layered fracture zone of the NNE-trending Lemachang overthrust structure. Host rocks are dolomites and limestones of the Middle Devonian Qujing Formation, and Cambrian and Ordovician siltstones and sandstones. Country rocks exposed in the area are Lower Cambrian to Upper Permian Emeishan basalts.
