Except for the Gongguan deposit, the important Sb deposits in China are concentrated inthis low-temperature metallogenic domain, constituting the Hunan-Guizhou-Guangxi-Yunnan Sb ore belt.In general this ore belt extends in the NNE direction, measuring 1 900 km or more in length and 200 kmin width. A total of 505 Sb deposits (or occurrences) are known, accounting for 85.5 % of the 关 键 词：deep-source SB MINERALIZATION YANGTZE massif.
