四川九龙县江浪铜矿田矿床地质特征、控矿因素及找矿方向

江浪铜矿田位于扬子地台西缘江浪变质核杂岩穹隆构造中。至今已发现里伍、黑牛洞等中、小型铜矿床7处,为扬子地台西缘地区铜矿集中产出区之一。对江浪铜矿田矿床的地质特征、矿石矿物组成、控矿因素等的研究结果表明,江浪铜矿田的铜矿床受江浪变质核杂岩穹隆构造中的多层次韧性剪切滑脱带控制,铜矿化、矿体主要赋存在韧性剪切滑脱带中。该区成矿条件优越,具有形成大型、超大型铜矿床的条件,找矿潜力巨大。铜矿体主要呈脉状、透镜状和似层状,矿床为中高温热液型铜矿床。本文在详细研究矿床地质特征、控矿因素、成矿过程与矿床成因的基础上,提出了矿田和区域找矿方向,为本区找矿有新的突破提供了新的思路。

GEOLOGICAL FEATURES,ORE-CONTROLLING FACTORS AND PROSPECTING DIRECTION OF THE JIANGLANG COPPER DEPOSIT IN JIULONG IN WEST SICHUAN

The Jianglang copper deposit is hosted in the extension ductile shear zones of the Jianglang metamorphic core complexes in southwestern margin of Yangtze platform.Up to now,7 copper deposits have been found in the area,such as Liwu and Heiniudong copper deposit,which shown the area is one of the very important clusters of mineral deposits in southwestern margin of Yangtze platform.It is controlled by the extensional ductile shear zones of the Jianglong metamorphic core complexes.Research on geologic charact...
