摘要
新一轮区调填图所获资料表明,加里东期花岗岩成因类型复杂多样,有岛弧花岗岩、同碰撞花岗岩及少量陆内造山花岗岩等,说明东昆仑东段在加里东时期经历了复杂的洋—陆俯冲、陆陆碰撞的动力学过程。
After a discussion on the geological features of Caledonian granites in the eastern sectorof East Kunlun, the authors held that the genetic types of Caledonian granites were very complex andabundant, including island - arc type, collission type and inner- continent orogenic type, and so on.All these reflect that the eastern sector of East Kunlun was subjected a complex dynamics process ofocean - continent subduction and continent - continent collision in Caledonian Cycle.
