| 摘 要： | 东昆仑东段都兰哈日扎地区出露比较典型的燕山期花岗闪长斑岩,斑岩体以少暗色矿物、多巨斑、石英斑晶具熔蚀现象、普遍见孔雀石化和地表"火烧皮"为特征。斑岩形成于后碰撞伸展构造环境,是加厚陆壳背景环境下的底侵、拆沉构造作用的结果。斑岩具全岩铜矿化特征,属于大陆环境下的斑岩型矿床。从其成矿地质特征、地球物理、地球化学特征和斑岩体深部矿化特征综合分析,该区具有寻找斑岩型铜矿的巨大潜力。

| Abstract: | Harizha is located in Dulan in east Kunlun, it developed typical Yanshanian granodiorite-porphy- ry. The porphyry body is characteristic of less melanocratie mineral, giant phenocryst, corroded quartz phenoeryst, widespread malachite mineralization and Fire-skin in surface. Porphyry formed after the colli-sion stretch tectonic environment, is the result of assault and heavy construction effect in the thick conti- nental crust background environment. Porphyry copper deposit with the rock change feature, belongs to the continent in the environment of porphyry deposit, from its metallogenic geological characteristics, geo- physical and geochemical characteristics and deep porphyry mineralization characteristic in the comprehen- sive analysis, it has enormous potential for porphyry copper. |
