THE Xikuangshan Sb ore deposit located in the central part of Hunan Province, China, is the only superlarge Sb deposit so far reported in the world, and is titled as the antimony capital of the world. The strataexposed in the Xikuangshan orefield are only Devonian to Permian Series. Except for a lamprophyre dykeseen in the eastern part, no igneous rocks outcrop within or around the mining district. Orebodies occurdominantly in the Devonian Shetianqiao Formation (D_3_s) and subordinately in the Qiziqiao Formation(D_2_q). The orebodies usually appear stratiform and stratoid in shape and are rather constant in boththickness and grade. The compositions of ores are simple. The metallic mineral is stibnite and the gangueminerals include quartz and calcite, with minor amounts of fluorite, barite and secondary gypsum. Theores are dominated by the quartz-stibnite type, the quartz-calcite-stibnite type and the calcite-stibnite
