| 中文摘要: |
| 湖南西部寒武系下统牛蹄塘组底部的含碳硅磷质黑色岩系主要由黑色碳质页岩组成,富集了多种有色金属、贵金属、稀有金属和稀土元素,是我国新类型的有色金属、贵金属的矿产资源和后备矿产资源,其中尤以钒的资源量最丰富,是湘西地区继锰和汞铅锌矿之后,又一最具优势和开发前景的矿产资源。研究表明,黑色岩系形成于扬子准地台东南缘之深水斜坡的缺氧环境,有机质含量高是其重要特点,钒在有机质中优先被结合。沉积环境的改变导致成矿作用的发生,生物地球化学作用是钒矿成矿的主导作用。矿床属于化学和生物地球化学沉积型钒矿。 |
| 英文摘要: |
| The black rock series at bottom of Lower Cambrian Niutitang formation mainly consists of black carbonaceous shale which contains not only Si, P, C, but is also rich in nonferrous, precious, rare-metals and REE, thus is a new type of non-ferrous, precious metal reserve in our country. Specially, the abundant V resource is another superior mineral product discovered after Mn, Hg and Pb-Zn deposit in the west Hunnan province. The black rock series was deposited under deep water anoxic reductive environment on the shelf of southeast margin of Yangtze paraplateform and is characterized by enrichment of organic substance. V is preferentially compounded with organic substance. Metallization was led by the change of sedimentary environment. Biogeochemistry plays an important part in formation of the V deposit. And the deposit belongs to chemical and biochemical sedimentary type. |
