Abstract The Shengou gold-antimony deposit, located in the western section of Middle Qilian metallogenic belt in Qinghai Province, belongs to Middle Qilian-Taibai formation subarea in terms of stratigraphic division. On the basis of field survey and test analysis, with comprehensive study on stratigraphy, lithology, structural conditions and magmatic rocks, it is considered that the deposit belongs to meso-epithermal mineralization with ore-orming fluids mainly of magmatic vapor-water and underground hydrates. The orebody occurrences are controlled by both structural fracture belts and rock mass. With multiple differentiation and enrichment of ore-forming elements due to multi-stage tectonic activity, the high grade gold-antimony deposit is formed with prospecting potential.
