Involvement of deep-source components in Sb mineralization on the southwestern margin of the Yangtze massif - A discussion on its possibility

摘要

Extensively developed on the southwestern margin of the Yangtze massif are epithermal deposits such as gold, silver, antimony, mercury, arsenic, uranium, copper and lead-zinc ore deposits, as well as barite, fluorite, iceland spar and rock crystal deposits, which constitute a unique low-temperature metallogenic domain. Except for the Gongguan deposit, the important Sb deposits in China are concentrated in this 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 km in width.
