中国及邻区印支运动特征及其意义

Indosinian Movement Characteristics and Its Significance in China and Neighboring Areas

通过概要论述印支运动在中国及邻区的表现特征,探讨了印支运动的主要成矿作用,指出印支运动首次使长期以来游离于全球主要大陆外的扬子、中朝、塔里木等小陆块拼合在一起,为新生代大型聚煤盆地的形成奠定了基础,也为燕山期和喜马拉雅山期二次大规模的对流地幔输入大陆事件奠定了重要基础,使之成为中国及邻区大陆上最重要的成矿时期。

Through the brief summarization of Indosinian movement characteristics in China and neighboring areas, discussed main mineralization during the movement. The study pointed out that the movement made the smaller landmasses of the Yangtze, Sino-Korean, and Tarim those isolated from main global continents for a long time then locked together. The movement has laid important foundations of Cenozoic large coal accumulation basins formation and two events of extensive convective mantle into continent during Yansha-nian and Himalayan stages, thus the most important mineralization period in China and neighboring areas.
