摘要
劣布铜矿为火山沉积喷流层控型铜矿床;矿体受比马组第四岩性段层位和角砾岩筒控制,容矿岩石为角岩、层夕卡岩和角砾岩,矿物组合简单,流体包裹体测试表明夕卡岩铜矿化形成深度小于典型的斑岩铜钼矿,显示矿床的剥蚀程度较低,对寻找斑岩型铜矿是有利的。
Liebu deposit is a volcanic Sedex stratobound copper deposit with ore bodies controlled by the 4th lithological member of Bima Formation and breccia pipe. It is hosted by hornfel, layered skarn and breccia. The mineralogy is simple. Fluid inclusion data reveal depth of the skarn type copper mineralization is less than that of typical porphyry copper mineralization and intense erosion did not take place here thus it is potential for further exploration of porphyry copper deposit.
