| 摘 要： | 四川省中厂铜矿位于扬子地台西南缘的康滇地轴中段,赋矿地层为中元古界下部的通安组,铜矿体赋存在通安组第二段和第三段中,铜矿体呈似层状,矿体围岩分别为白云石大理岩、石英变粒岩和含石英大理岩,地层中层间破碎带、滑动带和裂隙发育,并发生硅化、绢云母化、白云石化和褪色等热液蚀变,地层中碳质含量较高,矿床地质特征上判断,成矿经过沉积成岩期和构造-热液改造期,成矿物质为多期多来源,因此认为中厂铜矿床属于沉积-改造型铜矿床。

| Abstract: | The Zhongchang copper deposit is located in the Middle Proterozoic Lower Tongan formation in the middle of Kangdian axis at southwest margin of the Yangtze Platform. Ore bodies are lenticular or layeroid occurring in dolomite, quartz marble and quartz-bearing marble in the 2nd and 3rd member of Tong formation. In the strata are developed interformation fractural zone, sliding zone, fractures, and hydrothermal alteration, such as silicification, sericitization, dolomitization and decoloration and carbon content is high. Judged from the geological characteristics ore material of the deposit is multi-sourced and the metallogenic process includes sedimentary diagenesis and hydrothermal reworking and the deposit is a sedimentary reworking type Cu deposit. |
