藏北西双湖地区的下三叠统前人曾做过一些地质工作。笔者去年测制了较完整的下三叠统地层剖面,与上覆中三叠统和下伏上二叠统均为连续沉积。其岩性组合及生物面貌均可与华南地区对比,产有丰富的瓣鳃类化石。地层出露于西双湖—热觉茶卡一带,为一套碎屑岩、碳酸盐岩沉积,地层呈北西—南东向展布,露头连续,发育完整。原中科院文世宣等曾做过路线工作,将这套地层划分为硬水泉组和康鲁组(详见地层对比简表)。
The Lower Triassic in the Xishuangbanna region of northern Tibet have done some geological work. Last year, the author measured a relatively complete Lower Triassic stratigraphic profile, and overlying the Middle Triassic and underlying Upper Permian are continuous deposition. The lithology combination and biological appearance can be compared with the South China region, producing rich flap gill fossils. The strata are exposed in the area of Xishuang Shu - Rejiao Chaka, a set of clastic rocks and carbonate sediments. The strata are distributed from northwest to southeast, with continuous outcrops and complete development. Former Chinese Academy of SciencesWen ShixuanAnd so have done the route work, this set of strata into hard springs and Kanglu group (see stratum comparison table).
