| 中文摘要:察隅地区属多次构造变动地带，先后经历了５次构造变形的改造与叠加，主要在三叠纪－中侏罗早期受古特提斯封闭影响而形成，中侏罗世晚期后，进一步加强与定型而成为主动大陆边缘逆冲推覆、逆冲式褶皱造山带。由４个次级构造（－建造）单元组成。可分为４种构造变形相，在各构造单元中构成了变形序列。 |

| Abstract:The Zayü area is a polyphase structural deformation z one.It underwent five phases of structural deformation and superimpositior.It o riginated mainly under the influence of the closing of the paleo-Tethys.After th e middle part of the Mid Jarassic,it was finalized and became an active continen tal-margin thrust-type fold orogenic belt.It is composed foursecond-order struct ure(formation)units and may be divided into four toctonic deformation facies wh ich form a deformation sequence in each tectonic unit. |
