摘要
甘肃省阿克塞县化石沟铜矿是柴达木北缘缝合带上近年来发现并取得重大突破的斑岩型铜矿床。本文对矿床区域构造定位;区内近南北向弧形弯曲构造系列的形成机制及与成矿的关系;含矿浅成英云闪长斑岩的形成演化及其与成矿的关系;多种蚀变与矿化的关系以及矿床成因等方面进行了全面分析论证。这些认识有助于开拓区域上找矿的新思路。
Huashiguo copper deposit is a porphyry type copper deposit which was discovered recently,and it was made an important breakthrough in the suture-zone of the north-margin of Chaidamu Basin.In the article the writers made some academic analysis such as location of region tectonics of Huashiguuo deposit,forming mechanism of the structure in the region,forming and evolution of hypabyssal ore-bearing quartz-diorite porphyry,alteration,and relationship of them to mineralization.
