    摘要:

    羌塘盆地位于青藏高原腹地,侏罗系—白垩系分布广泛,但由于地处高寒地区,地层厘定工作一直以来较为薄弱,这限制了地质认识水平的提高。本文通过总结前人40年来的野外基础调查资料,结合近年来我们对羌塘盆地的最新研究成果,总结和评述了羌塘盆地侏罗纪—白垩纪的岩石地层格架,并简要探讨了各地质单元的沉积环境和沉积物源,并提出了羌塘盆地侏罗纪—白垩纪地层格架中存在的一些问题。

    Abstract:

    〗The Qiangtang Basin is located in the hinterland of the Xizang(Tibetan) Plateau. The Jurassic—Cretaceous strata is widely distributed. However, due to the high altitude and cold climate conditions, stratigraphic research is relatively weak, which limits the improvement of our level on geological knowledge of the Qiangtang Basin. This article reviewed the field survey data of published text in the last 40 years, combined with our latest works on the Qiangtang Basin, summarized the Jurassic—Cretaceous lithostratigraphic framework. And briefly discussed the sedimentary environment and provenance of each geological unit. In addition, we also put out some problems about the Jurassic—Cretaceous stratigraphic framework of the Qiangtang Basin.
