贵州三穗地区钒矿地质特征及成矿规律研究

Research on the Geological Characteristics and Metallogenic Laws of Vanadium Deposits in Sansui Area of Guizhou

总结贵州省三穗地区钒矿矿区地层、区域构造和区域岩浆岩特征,探讨矿区钒矿成矿规律。研究表明区内钒矿赋存在陡山沱组白云岩的上部以及老堡组和九门冲组的下部,含矿岩性为黑色炭质黏土岩;成矿来源主要是由于海底裂谷的热气流作用,携带深部钒等多金属元素向陆棚与台地运动、迁移,出现钒的横向分导现象;沉积下来的钒金属又在后期低温热液作用下,以水云母的形式存在,而炭质吸附的部分钒元素进入水云母晶格中,形成钒矿。

Summarize the characteristics of the stratum,regional structure and regional magmatic rock of the vanadium mining area in the Sansui area of Guizhou Province,and discuss the mineralization law of the vanadium deposit in the mining area.The results of the study indicate that the vanadium deposits in the region are located in the upper part of the Doushantuo Formation dolomite and the lower part of the Laobao Formation and Jiumenchong Formation.The source of mineralization is mainly from the hot air currents of the submarine rifts that carry deep vanadium and other metal elements to the shelf and platform to move and migrate,and the phenomenon of lateral separation of vanadium occurs.The deposited vanadium metal exists in the form of hydromica under the action of low-temperature hydrothermal fluid in the later stage,and part of the vanadium element adsorbed by carbon enters the hydromica lattice to form vanadium ore.
