云南下寒武统黑色岩系矿床研究现状及相关找矿问题探讨

Research and Ore Prospecting Problem of the Lower Cambrian Black Series in Yunnan Province,China

云南地区下寒武统黑色岩系分布广泛,组成多为黑色、灰黑色的页岩、炭质页岩、砂质页岩及硅质岩等。在黑色岩系中伴有镍、钼、铀、钒、银、硒、铂、钯、铜,铅、锌等元素的成矿和矿化富集。由于其特殊的形成时代及特殊的多金属组合特点,黑色岩系矿床一直是地质学家研究的热点。本文在收集分析国内外大量文献资料基础上,系统地对国内外黑色岩系及矿床分布、矿种及赋存形式、成矿模式、沉积环境进行了综述,总结了云南黑色岩系及矿床研究的现状及成果,指出了云南黑色岩系找矿勘查方面应注意的几个关键性技术问题。

The Lower black rock series are broadly distributed in Yunnan Province, China. The black shale series are mainly consisting of black shale, carbonate shale, arenaceous shale, siliceous shale and silicate. This black shale has been associated with Ni, Mo, U, V, Ag, Se, Pt, Pd, Cu, Pb, and Zu and other elements enrichment and mineralization. Ore deposit of black rock series has aroused much interest due to their specific age and poly-metallic combination. Based on a lot of information review, this thesis systematically introduces the black rock series, ore deposit distribution, Minerals, occurrence shapes, metallogenic model and sedimentary environment. It summaries the research results and current situation of black rock series and ore deposit in Yurman. At last, this paper points out several prospecting and exploitation technical questions on the black rock series in Yunnan.
