青海省中南沟铅锌矿区地质特征与成矿机理研究

A Research on Geological Characteristics and Metallogenic Mechanism of Lead and Zinc Mining in Zhongnan Ditch of Qinghai Province

矿区位于北祁连加里东造山带与中祁连隆起带接壤的大坂山断裂带北侧。区内奥陶纪富钠的细碧—角斑岩系发育,形成海相火山—沉积型铅锌矿,奥陶纪火山—沉积岩建造是本区主要的含矿建造之一。对矿区地质特征进行深入分析,进而对矿床成因,控矿因素,矿化富集规律,找矿标志进行深入研究,对以后的工作具有十分重要的参考价值。

The mining area is located in the north of Qilian -caledonian belt and the large mountain fault zone which is bounded by the middle Qilian, which borders on the central Qilian. Ordovician in the area of rich sodium fine garden - keratophyre series development, formation of Marine volcanic - type lead - zinc deposit, ordovician volcanic - sedimentary rock formation is one of the major ore built. In this paper, the mining area geological features in- depth analysis, and then to the genesis of ore deposits, ore- controlling factors, mineralization enrichment regularity and prospecting marks an in - depth research, have very important reference value for the following job.
