Xikuangshan Antimony Deposit, Hunan
This is the world’s largest antimony deposit. It is located in Lengshuijiang City, Hunan Province, along the southern margin of the Xiang Zhong (Central Hunan) basin (also called the Xiang Zhong sag), the northern margin of Baima Mountain-Xialong Mountain and the western end of the arcuate tectonic belt in Qiyang. The ore field has a NNE trend and is composed of four ore bodies: Laokuangshan, Tongjiayuan, Wuhua and Faishuiyan. The ore bodies are located in the silicified limestone of the Upper Devonian Shetiaqiao Formation. The total proved antimony reserves of the deposit are more than two million tons. The scale of the deposit is so large that it has been called the ‘World’s Antimony Capital’. When it was discovered at the end of Ming Dynasty, the ore was mistakenly interpreted as tin; hence, it was given the name Xikuangshan, which means ‘tin ore mountain’.
