| 摘 要： | 桦树沟铜矿床是近年来在甘肃走廊南山下古生界变质火山—沉积岩系内硅铁建造中新发现的一类富铜矿床。通过对该矿床的地质特征和一系列测试、分析数据的研究对比,认为该铜矿属海底热水沉积(变质)—后期热水迭加改造成因,并总结了桦树沟(式)铜矿床的成矿控制条件和找矿评价标志,认为在走廊南山中段下古生界硅铁建造中具有进一步找桦树沟式铁铜型铜矿床的良好前景。

| Abstract: | Huashugou copper deposits are a group of copper-rich deposits newly discovered in siliceousiron formation located in lower palaeozoic metamorphosed volcanic-sedimentary rocks in South Mountains, Gansu Corridor. It has been considered from the study of the geological characteristics and a series of data measured that Cu deposit has the genesis feature of submarine hydrothermal sedimentary (metamorphosd) -reworked by poststaged hot water. Through the summary of ore-controlling conditions and prospecting evaluation criteria of Huashugou-type Cu deposits, good perspective for Huashugou Fe-Cu type Cu deposits in the early Palaeozoic siliceousiron formation in the middle portion of South Mountains in suggested. |
