| 摘 要： | 矿床具斑岩型铜矿化蚀变特征,从岩体中心向外,蚀变呈环带状分带发育,依次为强硅化带→钾硅化带→绢英岩化带→青磐岩化带。矿化在浅部表现为断裂破碎带控制的热液脉型Cu、Au、Pb、Ag矿床,深部则为斑岩型Cu、Mo矿床。

| Abstract: | There are characteristics of the alteration of porphyry Cu deposit in Lujiacun Ag - Au multimetallie deposit, Xianggelila. The aheration is in zonation distribution outwards from the centre of rock body, ie, strong silicification zone→K silicilication zone→sericitolitization zone→propylitization. In the shallow paint, the metallogenesis is controlled by the fault zone and the appearance is the hydrothermal Cu, Au, Pb, Ag veined deposit. In the deep part, it is the porphyry Cu, Mo deposit. |
