黔北牛蹄塘组黑色岩系中的矿产特征及找矿远景分析

Mineral Character and Prospecting Potential in the Black Rock Measures of Niutitang Formation in North Guizhou

黔北牛蹄塘组为早寒武世梅树村期沉积的一套黑色岩系,其下段(习称"黑层")普遍含镍、钼、钒、铀、磷等多元素矿产,钒分布普遍常赋存于"黑层"的简单岩性组合区,而镍、钼富集于"黑层"的复杂岩性组合区,磷、铀则不受"黑层"岩性组合的控制。本文通过对黔北"黑层"含矿组合、合矿性和典型矿床地质特征及岩相古地理环境的分析和总结,认为牛蹄塘组下部"黑层"在黔北具较大的找矿空间和找矿前景,进而指出了找矿方向和找矿远景区。

Niutitang formation in north Guizhou is a black rock measures in Meishucun period,Early Cambrian, it contains Ni,Mo,V,U,P and other elements in the lower segment,vanadium usually occurs in the simple lithology association are of ＇black layer＇,nickel,molybdenum concentrated in the complex area,but phosphor,uranium is not controlled by the ＇black layer＇.In this paper,it analysis and summarize the ore bearing association,ore bearing potentiality and typical deposit geologic characters of ＇black layer＇,and lithology paleogeographic environment,it＇s thought there are big prospecting space and potential of lower segment Niutitang formation of ＇ black layer＇ in north Guizhou,then the prospecting target is carried out.
