中国白垩纪特提斯区指的是在白垩纪时期,我国西藏大部、新疆塔里木盆地西沿及其它相邻的被海水淹没过的地区,它是特提斯带东部的组成部份。对这一近百万平方公里地区内的白垩系地层进行研究之所以重要,不仅由于这里有若干重要矿产资源,而且因为这里的白垩系与极复杂的构造现象一如著名的外来岩块带或混杂岩带一有密切的关系。即使 The Cretaceous Tethys area in China refers to the areas that were mostly submerged by seawater during the Cretaceous period, most of Tibet in China, the western edge of Tarim Basin in Xinjiang and other parts of the Tethys zone that are part of the eastern part of the Tethys Zone.
