黔东北地区钒矿成矿地质特征及成矿预测

黔东北地区沉积型钒矿与寒武系下统九门冲组(1jm)黑色岩系密切相关。本文通过对该区钒矿产出的区域地质背景、含矿岩系、赋矿岩石地化特征,岩相古地理环境、矿床时空分布和矿体产出特征等进行综合分析,表明该区具有很好的成矿地质条件。根据本区找矿实践和成矿相关理论、控矿因素等综合研究,圈定了松桃石梁—孟溪、松桃盘石—江口桃映—坝黄、印江永义、铜仁漾头—万山黄道、石阡坪山—聚凤5个成矿有利远景区,为指导今后在该区开展钒矿找矿工作,取得更大的找矿突破提供参考。

Geological Characteristics and Metallogenic Prediction of Vanadium Deposit in Northeast Guizhou

In the northeast Guizhou, sedimentary vanadium deposit has deep relation with black rock senes of Jiumenchong formation of Lower Cambrian. By analysis regional geological background, ore - bearing rock series, geophysical feature of ore - bearing rock, lithofacies - paleogeographical environment, temporal - spi- tial distribution, orebody occurence feature, it reflects that the metallogenic condition is good, according to the exploration practice, relative theory and ore - controlling factors, Shiliang - Mengxi, Panjiang - Taoying - Bahuang, Yongyi - Yangtou - Huangyi, Pingshan - Jufeng ： 5 mineral prospecting areas are targeted, it will afford guidance for vanadium exploration in this area in the future.
