从帕米尔至贝加尔,是大陆内部地震活动最集中的地区之一。近百年,发生过七级以上地震30次。因此,它引起国内外地学界的广泛研究。笔者认为,这是与该区岩石圈构造演变和最新地壳块体运动分不开的。据地史时期出现的强烈火山活动,基性-超基性岩浆上升,巨厚的复理石——火山岩建造等情况分析,中亚大地存在着许多古缝合线构造,它们把众多的岩石圈块体接合起来,形成现
From Pamir to Baikal, it is one of the areas with the highest concentration of seismic activity in the continent. Nearly a century, there have been more than seven earthquakes 30 times. Therefore, it has caused extensive research in the field of science at home and abroad. In my opinion, this is inseparable from the evolution of lithospheric structure and the latest crustal movement in the area. Based on the analysis of the intense volcanic activity, the basic-ultramafic magma uplift and the thick flysch-volcanic rock formation during the geochronological period, there are many ancient suture structures in the Central Asia. They connect many lithosphere Block together to form now
