| 摘 要： | 文章以勉略带为中心，概述了勉略带组成、分布，重点简介了组成勉略（康县一略阳段）中间混杂带的三个逆冲推覆（混杂）岩片带的岩石构造单元和构造变形序列以及产于混杂岩带中的蛇绿岩地质组成、岩石学和地球化学特征。在上述基础上结合南秦岭、摩天岭、龙门山、扬子西北缘晓华力西以来的变形构造几何学格局和古特提斯北部陆缘（古中国西南缘）构造组成轮廓后，将本区厘定为特提斯造山系一部分，建立两条结合带，双向汇聚体制，两列造山带（秦岭造山带、松潘─甘孜造山带），和一个共有的前陆（扬子西北缘）区域造山模型。

| Abstract: | ON the basis of discussion of component and distribution in Mian Lue belt, the following characteristics are studied closely, which are not only the unit of rock-structure, the deformation succession of structure in three thrust-nappe sheet belts, but also the geological component, the characteristics of petrology and geochemistry for ophiolite in hybrid rock belts. It is thought that this belt is part of the Tethyan mountain ridges. This conclusion is made from the study for the geometric characteristics of deformation structure in the north Qinling, Mo Tian Ling, Long Men Mountain, the north-west Yangtze, and the west part of paleo-Tethyan since later Variscan. At same time, two bound zone, bilateral convergent boundary, two orgenic zone (Qinling, Song Pan-Gan ZI) and precontinental (the north-west part of Yangtze) regional orgenic model are established iri this paper. |
