西昆仑北带蛇绿岩的地球化学特征及其大地构造意义

在西昆仑造山带的北侧存在着一条西起盖孜，向东经奥依塔格、库地、苏巴什至祁曼塔格的蛇绿岩带。在详实的野外考察工作和充分总结已有研究资料的基础上，通过对该蛇绿岩带岩石化学、地于化学特征的分析，认为它对西昆仑造山带大地构造演化的研究提供了重要的信息，反映了西昆仑造山带曾经历了由统一陆块在震旦纪时的破裂到喜马拉雅期的强烈推覆和走滑等过程，从而奠定了西昆仑现今的构造格架。

Signification About the Ophiolite's Geochemistry Characteristics and It's Tectonic Significance in the Northern Belt of West Kunlun

From Gaizi, Aoyitage, Kudi, Subashi to Qimantage, there is a important ophiolite strip in the northern belt of West Kunlun. Based on the abundant information about every epoch ophiolite's petrochemistry, geochemistry characterictics, which distributed over West Kunlun area, after a detailed field inspect, the author regarded that the ophiolite strip gave so much important information about the tectonic evolution of West Kunlun orogenic zone.It has been told that the West Kunlun orogenic zonehad come through splintering during Sinian and shaped during the period of Himalaya after violent napping and strik-sliping.
