Features of alteration and mineralization in the Chundu porphyry copper deposit, Xianggelila, Yunnan Province
摘要
Abstract
The Chundu porphyry copper deposit lies in the southernmost famous Zhongdian-Yidun island arc of the Indosinian Orogeny. There are cropping-out of multi-legs rock mass composed of diorite porphyrite and granodiorite-porphyly in the orefield. The granodiorite-porphyry is granodiorite -porphyry metallogenic rock mass in the orefield. There are fierce alteration of wall rock and visible zonality of alteration in the orefield sun＇ounding the metallogenic rock mass. There exist kali silicification zone→sericitolite zone~silicification and biotitization zone→silification zone→propylitization zone→ sericitization and argillization zone ,from centre to outside surrounding the metallogenic rock mass. The alteration is closely related with mineralization in this area. The degree of mineralization depends on the types of alteration and the occurrence of orebody is controlled by the distribution of alteration zones. So the study of alteration of wall rock will provide important evidence for further prospecting in the orefield.关键词
