| 摘 要： | 根据新藏公路沿线实际观察资料及前人研究成果，着重通过库地北构造带两侧变质岩、岩浆岩及构造古环境特征的对比，以及对构造带中蛇绿岩的地质特征和形成环境的分析，初步探讨了该构造带的大地构遣演化。认为库地北构造带为古昆仑洋盆消减、封闭的最终位置，是形成于志留纪的板块聚合碰撞缝合带，代表着早古生代阶段塔里木板块的南部边界，也是控制塔里木盆地西南部和西昆仑山地区区域构造格架的重要构造带。

| Abstract: | On the basis of on-the-spot investigation and the available data along Xingjiang-Tibet highway,this paper studied the geological characteristics of the metamorphic and magmatic formations and tectonic setting on both sides of North Kudi structure belt in wesem Kunlun Mountains, analyses the geological characteristics and tectonic setting of ophiolites in the structure belt, discusses the geotectonic significance of the structure belt. The results show that the North Kudi structure belt was the site of subduction and closure of the PalesKunlun oceanic basin, also a convment plate suture formed in the Silurian period, the southern boundary of the Tarim plate in the bor Paleozoic, and was an important structure belt which controls the regional tectonic configuration of southwestem Tarim Basin and western Kunlun area. |
