贵州省开阳县钼镍钒矿的基本特征

本文从已有资料入手,以典型矿点为例子,结合系统的采样工作,分析了开阳县境内牛蹄塘组含矿岩系及矿床基本特征,认为开阳县境内的牛蹄塘组有两个岩石组合类型,即硅质磷块岩、炭质页岩、黄铁矿、白云岩组合和硅质磷块岩、炭质页岩组合;牛蹄塘组黑色岩系内的钼镍钒富集有一定的规律性,硅质磷块岩、炭质页岩组合中的钼镍钒含量普遍较高,钼镍矿层厚度较稳定,品位较高;并认为今后在开阳找寻钼镍钒矿的主要靶区是翁昭背斜及龙水的牛蹄塘组。

The Basic Characteristic of Mo-Ni-V Ores Deposit in Kaiyang, Guizhou

Started with present information, in case of the typical occurrences, joining systematic sample collection, the fundamental characteristics of ore-bearing rock series and deposits of the Niutitang Formation in Kiayang was analyzed in this paper, there are in consideration two types of rock combination of Niutitang Formation in Kaiyang, including: combination of siliceous phosphorite, carbonaceous shale, iron pyrites and dolomite, and of siliceous phosphorite and carbonaceous shale. The enrichment of molybdenum, nickel and vanadium in black rock series of the Niutitang Formation unfold certain regularities that the contents of molybdenum, nickel and vanadium in the combination of siliceous phosphorite and carbonaceous shale are widely high and the horizons of molybdenum and nickel ore shale are steady in thickness with good grade; in addition, it is considered that the main target areas to future seeking for molybdenum, nickel and vanadium highlight the Wengzhao anticline in Kaiyang and Niutitang Formation in Longshui.
