Shizangsi gold-antimony deposit located in Sanjiang arc basin in northern Tibet (Qiangtang) of mainland China in late Paleozoic and western end and northern margin of Xiqingshan mountain in late Paleozoic basin. This deposit is symbiosis of gold and antimony. The ore bodies were controlled by tectonic fractural belt with similar plate and lenticular types. Native gold has close relation with stibnite and quartz. Gold inclusions accounted for 50% or more. Intergranular gold and fissured gold have paragenetic relation with stibnite and quartz. The alteration of country rocks were composed of silicification, sericitization, pyritization and limonitization. Shizangsi gold-antimony deposit is similar with Dachang gold-antimony deposit. In the period of forming Tibetan collision orogenic belt, magmatic hydrothermal migrated along the deep faults, happened atmospheric water cycle, extracted Au and Sb minerals, and accumulated gold-antimony ore bodies in the areas with appropriate geophysical and geochemical conditions. It was the shallow deposits of orogenic gold and antimony deposits.
