湘西北黑色岩系中钒镍钼矿床地球化学特征研究

通过对湘西下寒武统黑色岩系中的钒镍钼矿床的地质特征、矿石的微量元素地球化学特征、稀土元素的地球化学特征、稳定同位素地球化学特征等研究,认为赋矿地层为下寒武统木昌组。钒、镍、钼矿床的成矿物质来源为多源,稀土元素的分布和硫同位素的组成表明湘西下寒武统黑色岩形成于缺氧的陆架边缘浅海环境,海底热液活动为其提供了丰富的物质来源。

Geology Geochemical Characteristics of V-Mo-Ni Deposit in Black Shale Series in Western Hunan

Through the research of geological features, trace elements geochemical characteristics, rare-earth elements geochemical characteristics and the stable isotope geochemical characteristics of V-Mo-Ni deposit in Lower Cambrian black shale series in Western Hunan, it shows pay lead locate in the Lower Cambrian Muchang formation. The source of the V- Mo-Ni deposit is multiple source. According to the distribution of rare-earth elements and sulfur isotope composition, the depositional environment of Lower Cambrian black shale series in Western Hunan is anoxic neritic shelf. And submarine hydrothermal solution supply the abundant minerogenic materials.
