重测西藏南部江孜床得剖面后发现地层层序与前人认识完全相反，不只含上白垩统，还包括中—上侏罗统和整个白垩系；重新厘定了宗卓组、加不拉组，新建床得组，它们分属晚坎潘期—马斯特里赫特期、贝里阿斯期—三冬期和早—中坎潘期；由下向上可识别出６套沉积组合：安山岩层、黄层、黑层、白层、红层及滑塌层，大致对应于下热组（Ｊ２ｘ ）、维美组（Ｊ３ｗ ）、加不拉组（Ｋ（１－ ２）ｊ，床得浦段＋ 机布里段）、床得组（Ｋ２ｃ）、宗卓组（Ｋ２ｚｎ） The reanalysis of the Gyangze bed profile in southern Tibet reveals that the stratigraphic sequence is completely opposite to that of the predecessors, including not only the Upper Cretaceous but also the Middle-Upper Jurassic and the entire Cretaceous. The Zongzhuo, , A new beddeck, belonging to the late Campanian-Maastricht, Berrias-three winters and early-middle Campanian stages; from bottom to top, six sedimentary assemblages were identified: andesite Layer, the yellow layer, the black layer, the white layer, the red layer and the slip layer correspond roughly to the lower heat group (J2x), Vimicu group (J3w) Pu paragraph + machine cloth section), bed group (K2c), Zong Zhuo group (K2zn)
