摘要:
西藏冈底斯成矿带是我国最重要的资源接续基地之一，其地质工作程度相对较低，位于班公湖–怒江缝合带与雅鲁藏布江缝合带之间。受板块俯冲和碰撞作用的影响，冈底斯成矿带内岩浆活动强烈，在冈底斯火山–岩浆弧带形成了铜、铅、锌、钼、金多金属等矿床组合，东西向分布的矿床在局部区域具有成群聚集的分布特征，在区域上形成了5个超大型矿集区：雄村铜金矿集区，厅宫–冲江铜多金属矿集区，甲玛–驱龙–邦铺铜多金属矿矿集区，蒙亚啊–洞中拉–亚贵拉多金属矿集区，程巴–努日钨钼铜矿集区。本文在前人研究的基础上，试图总结西藏冈底斯成矿带在喜山期岩浆活动与成矿作用等方面的研究新进展，为冈底斯成矿带作进一步进行地质勘查评价工作部署及找矿突破提供依据。
The Gandise Metallogenic Belt is one of the most important resources in the base in our country, the degree of geological work is relatively low, and it is located between the class—nujiang suture zone and yarlung zangbo river suture zone. Affected by the plate subduction and collision, the magmatic activity of the Gandise Metallogenic Belt is strong; and the arc of volcanic zone formed copper, lead, zinc, molybdenum, gold polymetallic ore deposit combinations in the Gandise Metallogenic Belt. The distribution of the east-west deposit has gathered in the local area distribution characteristics, and on the area formed five super-large ore concentration area: Xiongcun copper and gold mine area, Tinggong-Chongjiang Cu-polymetallic mine zone, Jiama-Qulong-Bangpu Cu- polymetallic mine zone, Mengyaa-Dongzhongla-Yagui Cu-polymetallic mine zone, Chengba-Nuri W- Mo-Cu-polymetallic mine zone. On the basis of previous studies, this paper attempts to summarize the new development of research for the magmatism and mineralization in the Himalayan period in the Gandise Metallogenic Belt, and provide basis of further geological prospecting evaluation work deployment and prospecting breakthrough.
