西藏工布江达县塔桑郭铜钼矿矿床地质特征及矿床成因分析
|
摘要
塔桑郭铜钼矿位于雅鲁藏布缝合带以北,班公湖—怒江结合带以南的一条巨型冈底斯带构造—岩浆岩带上,在对该矿区的成矿地质背景进行讨论的基础上还对矿床地质特征进行了研究,矿体特征受构造影响明显。通过地球物理特征、地球化学特征分析,说明成矿物质主要来源于区内叶巴组、英安岩、晚白垩世斑状花岗闪长岩。
The tasang Guo copper molybdenum deposit is located in the north of the Yarlung Zangbo Suture Zone, combined with the Bangong Lake Nu River with a giant Gangdise tectonic belt of the southern magmatite belt, the basis for discussion in metallogenic geological background of this area on the geological characteristics of the deposit of ore body characteristics is obviously controlled by structure. The geophysical and geochemical characteristics analysis shows that the ore-forming materials mainly in the region of Yeba group, dacite, Late Cretaceous porphyritic granodiorite.
