喜马拉雅碰撞造山作用与(超)大型矿集区的形成:科学问题与思考

青藏高原及邻区是中国唯一的一块具有世界规模级的成矿富集区 ,迄今所发现的大型、超大型矿床 /矿集区 ,在时间抑或空间上均与喜马拉雅碰撞造山作用有着密切的联系 ,反映了与喜马拉雅碰撞造山作用过程相伴随的青藏高原周边及内部岩石圈薄弱地带的壳幔置换过程、层圈交换作用、流体活动及其地球化学分馏过程 ,是控制大型、超大型矿床 /矿集区形成的主要因素。青藏高原成矿大陆动力学研究是阐明该区矿产资源分布规律和进一步发现大型、超大型矿床 (矿集区 )的科学基础

HIMALAYAN COLLISION OROGENESIS AND FORMATION OF THE LARGE ENRICHED MINERAL DIST RICT: SCIENTIFIC PROBLEMS AND THINKING

The Qinghai Tibet plateau including its adjacent regions is an only enriched mineral district of world scale in China. Large and super large ore deposits discovered to date in the plateau and its adjacent regions are spatially and temporally associated with the Himalayan collision orogenesis. This reflects that the crust mantle replacement, hydrosphere lithosphere exchange, fluid activity and accompanied geochemical fractionation in the periphery and within the plateau where a weak lithosphere occurs are the main factors controlling the formation of the large enriched mineral district. The research on the ore forming continental dynamics of the plateau is the foundation for understanding the law of the distribution of mineral resources and for further discovering the large and super large ore deposits in the plateau.
