摘要
通过对赫章可乐铜矿化带进行野外地质调查、赋矿围岩及铜矿石采样、化学成分分析、矿物成分分析、X衍射分析等,开展了铜矿石的物质组成研究。矿石含铜品位为1.67%-3.88%.综合分析常量元素和XRD测试结果,得出赋矿围岩-飞仙关组砂岩为海相碎屑沉积形成。蚀变岩型铜矿石中黏土矿物含量高,是导致蚀变岩型矿石中铜含量及稀土元素富集增高的原因。
Through field geological investigation,Sampling,chemical composition analysis,composition analysis by X-ray diffraction and so on,the chemical and mineral composition of rocks and ores have been researched.According to the results of analysis,the percentage of copper in the ores ranged from 1.67% to 3.88%,Judging from the results of chemical composition analysis and XRD,we draw the conclusion that sandstone is formed in ocean,the percentages of clay mineral is very high both in rocks and ores,and it is the reason of copper and REE are rich in the ores.
