喀喇昆仑—唐古拉地层分区的北界沿塔什库尔干、泉水沟、可可西里山、玉树一线;南界沿班公湖、改则、奇林湖、索县、类乌齐一线。区内侏罗系发育,大致呈近东西向条带状分布,以浅海相碳酸盐岩和碎眉岩为主,间有海陆交互相碎屑岩沉积,最大厚度可达5,000—6,000米,构造线方向大体与山脉走向一致,为北西西—南东东向,为我国海相—海陆交互相侏罗系重要地区之一。
The Karakorum-Tanggula stratigraphic sub-region borders along the Topkulgan, spring ditch, Kekexili Mountain and Yushu line; the southern boundary of the Karakorum-Tanggula stratigraphic line stretches along Bangong Lake, Gaize Lake, Qilin Lake and Suoxian County. The Jurassic in the area developed roughly in the shape of a strip of east-west distribution, mainly of shallow marine carbonate rocks and crushed eyebrows, with sedimentary facies between marine and terrestrial clastic rocks with a maximum thickness of 5,000-6,000 meters. The direction of tectonic line generally coincides with that of the mountain range, which is from north west to west - south east to east, and is one of the important areas of marine-marine-continental interaction Jurassic in China.
