摘要：燕山—喜马拉雅期构造运动,引起印度板块与欧亚板块剧烈碰撞、太平洋板块向东俯冲与美洲大陆向西漂移,产生了“加厚旋涌”效应,即下地壳的加厚并深插上地幔软流圈,改变了软流圈运动方式而上涌,伴随强烈的岩浆活动和成矿物质上涌,完成了大规模成矿作用,在特提斯-喜马拉雅地区和太平洋东部边缘产出世界级超大型斑岩铜矿系列.初步提出太平洋东部边缘成矿作用明显超过特提斯-喜马拉雅地区原因.
The Yanshanian-Himalayan tectonic movement causes the violent collision between Indian Plate and Eurasian plate,the eastward subduction of Pacific Plate and westward drift of American Continent,and results in the“thickening swirl upwelling”effect,that means,the thickening lower crust inserts deeply to the upper mantle asthenosphere to change the movement mode of asthenosphere and cause upwelling,accompanied by intense magmatism and upwelling ore-forming materials,then the large-scale mineralization is completed with world-class super-large porphyry copper series occurred in the Tethys-Himalayan region and the eastern margin of Pacific Ocean.The mineralization in the eastern margin of Pacific Ocean is significantly more than that in the Tethys-Himalayan region.The reason is preliminarily discussed in this paper.
