    东昆仑与西昆仑地质构造对比研究之刍议

    Comparative study of the geological structure of the Eastern and West Kunlun Mountains

    • 摘要: 初步总结了昆仑造山带地质构造的四大特点和东、西昆仑地质对比的三大线索,重新厘定了构造单元,并进行了对比。提出了昆仑造山带研究的重要意义及研究的基本思路。指出昆仑造山带是在老的加里东造山带基础上重新解体裂妥为洋又拼合的地带,是一个原、古特提斯洋陆转换的转换承接地带。昆仑造山带保存了从原特提斯洋消亡后,由碰撞造山到山脉老化再次裂解这一大陆构造演化阶段的许多信息,可能是我们认识中国大陆乃至欧亚大陆如何通过这种转换实现洋陆转换,把各个陆声拼接在一起的一个重要窗口。对昆仑造山带的解剖对现今仍处于碰撞后发展阶段的青藏高原的研究及今后的找矿都具有指导意义。

       

      Abstract: This paper preliminarily summarizes four major characteristics of the geological structure of the Kunlun orogenic belt and three major clues to the geological correlation of the East and West Kunlun and redefines the tectonic units and makes a correlation of them.It proposes the important significance for the study of the Kunlun orogenic belt and the basic idea for its study.It is pointed out that the Kunlun oro-genic belt is a zone formed by the break-up of the older Caledonian orogenic belt into oceans and again amalgamation of them and a transition-junction zone of ocean-land transition of the Proto -Tethys and Paleo -Tethys.The belt has conserved much information about the tectonic evolution from collisional orogeny to mountain aging and break-up.It is probably an important window through which we may get an understanding of how the continent of China and even the Eurasian continent achieved the ocean-con-tinent transition through the aforesaidtransition and junction to amalgamate various continental blocks and its analysis has guiding significance for the study of the Qinghai-Tibet Plateau that is presently still in the post-collision development stage.This complex transition-junction zone is also a very favorable zone for mineralization.
