特提斯洋的两个部分——北部的古特提斯和南部的新特提斯是十分不同的。前者的关闭与后者在晚古生代—早中生代的张开是一致的,或者前者的关闭就是导致后者张开的原因。由于中国和印度这些大型板块的裂开而形成的陆块彼此作用,并与大型克拉通块体相互作用,从而造成了亚洲和东南亚褶皱带。中部伊朗、西藏和掸邦—西马来都是隶属于大冈瓦纳的印度—阿拉伯板块的一部分,它们裂离而形成了新特提斯。这些块体,加上古特提斯的其它块体,减小了特提斯洋的宽度,使之比原来设想的为窄。亚洲的一些造山幕与俯冲带及碰撞带的不断向南南西迁移有关。所形成的褶皱带,除喜马拉雅十分独特,系受到改造的微大陆外,其它褶皱带,从东南亚到中西亚在地质和构造发育方面皆可相比较。
The two parts of the Tethyan Ocean - the ancient Tethys in the north and the new Tethys in the south - are quite different. The closure of the former coincides with that of the latter during the Late Paleozoic-Early Mesozoic, or the closure of the former is the cause of the latter’s opening. The land blocks formed by the rifting of these large plates of China and India interact with each other and interact with large craton blocks, resulting in fold zones in Asia and Southeast Asia. Central Iran, Tibet and Shan State - West Malaysia are all part of the Indian-Arabian plate that belongs to Ongunamwana and they split to form Neo-Tethyan. These blocks, combined with the other blocks of the ancient Tethys, reduced the width of the Tethys to narrower than originally thought. Some of the mountainous origens in Asia are associated with the continuous south-west migration of subduction and collision zones. The fold belt formed, except the Himalayas is very unique, is the transformation of micro-continental, other fold belt, from Southeast Asia to Central and Western Asia in the geological and structural development can be compared.
