摘要
冈底斯斑岩铜矿带是近年来中国在世界三大斑岩铜矿带之一的喜马拉雅—特提斯成矿域中铜矿找矿取得重大突破的斑岩成矿带。驱龙等大—超大型斑岩铜矿床的发现与评价,标志着一个超千万吨级的斑岩铜矿勘查开发基地已经初步形成。笔者在重点介绍近年来驱龙、朱诺、冲江、吉如等斑岩铜矿最新找矿成果的基础上,对该带控岩控矿构造、含矿斑岩及其源区特征、成矿规律、成矿系列、成矿时代等主要理论研究成果进行了归纳与总结,并对其勘查和研究工作中存在的不足以及今后的努力方向提出了建议。
The Gangdise porphyry copper metallogenic zone belongs to the Himalaya-Tethyan metaUogenic domain-one of the three porphyry copper metallogenic belts in the world, where a major breakthrough has been made in mineral exploration in recent years. The Gangdise zone is also a porphyry metallogenic zone where a major breakthrough has been made in copper exploration in China. The discovery and evaluation of a number of large and superlarge porphyry copper deposits such as the Qulong deposit signifies the primary formation of a new base of exploration and exploitation of over ten million tons of porphyry copper ores. The paper mainly introduces the latest achievements and experience in exploration of the Qulong, Zhunuo, Chongjiang and Jiru porphyry copper deposits in the Gangdise belt, and on that basis, it summarizes the main results of theoretical research on the rock- and ore-controlling structures, features of ore-bearing porphyries and their source regions, metaUogenic characteristics, metallogenic series and mineralizing ages in this belt and at last presents some thoughts and suggestions on the disadvantages and future direction in the copper exploration and theoretical research.
