Abstract:
Guangxi antimony deposits resources are rich, which have become one of the dominant minerals in Guangxi. In order to investigate its metallogenic regularity, the authors of this paper have comprehensively summarized the Guangxi antimony deposits exploration, development, resource distribution, deposit genesis, spatial distribution characteristics and metallogenic regularity. The antimony deposits in Guangxi are divided into three genetic types, including magmatic hydrothermal type, epigenetic middle-low temperature hydrothermal type and weathering type, among which the magmatic hydrothermal type is the main type. 7 fourth-order genetic types are divided on the basis of the third-order genetic types, among which the compound cassiterite-sulfide antimony deposits are the largest, and most closely related to magmatic hydrothermal mineralization. In addition, the Guang-xi antimony distribution and enrichment are jointly controlled by the four in one, including the strata, structure, magmatic rocks and contact zone. These antimonies were mainly enriched in Dianqiangui passive continental margin tectonic units and Xiangzhong-Northern Guizhong (depression) metallogenic belt, and the antimony deposits with industrial value mainly occur in the Devonian system, which burst in Late Yanshanian.
