| 摘 要： | 深沟金锑矿床位于青海省中祁连成矿带西段，地层划分属于中祁连-太白地层小区.在野外工作和室内测试分析的基础上，通过对区内不同地层、岩性特征、构造条件、岩浆岩等方面的综合研究分析，认为该矿床属中-低温热液成矿，成矿热液主要为岩浆汽水热液与地下水合物.矿体产状受到构造破碎带与岩体的双重控制.由于多期次地质构造活动影响，区内成矿元素受到了多次分异、富集，部分地段矿体品位较富，是一处具有找矿潜力的金锑矿床.

| 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. |
