The goals of the thesis are mainly to investigate the structural profile at baila village in indus - tsangpo suture zone , and to provide us with effective reference information about deformation history of indus - tsangpo suture zone based on studies on petrology and petrofabric analysis of quartz in addition to detailed field observations 针对上述问题，本文进行了以下研究：本文以雅鲁藏布江结合带内部的“白拉村结合带构造剖面”为重点研究对象，在野外详细观测的基础上，通过室内岩石学研究和石英组构分析，为雅鲁藏布江结合带的变形历史提供了有效的参考信息。

Indus - tsangpo suture zone is the joint of indian plate and eurasia plate . the study on its evolution history can provide us dynamic evidence for continent - continent collision between indian plate and eurasia plate . then what is the formation mechanism and deformation history for the indus - tsangpo suture zone 雅鲁藏布江结合带是印度板块和欧亚板块碰撞的结合部位，研究其演化历史能够为解释印度-欧亚板块的陆-陆碰撞提供动力学方面依据，那么本区雅鲁藏布江结合带的形成机制和变形历史又是怎样的呢
