位于西藏冈底斯西部嘎尔县狮泉河地区的昂杰组和下拉组属于冈底斯地层亚区。在昂节组中已发现牙形刺，它们可以确定该组的年龄为早二叠世至中二叠世。下拉组的时代可能是中二叠世晚期。本区是否存在晚二叠世海相沉积仍有待确定，但有可能是下拉组下部与昂节组上部部分重叠。更重要的是，这项研究发现了典型的冈瓦周冷水相牙形刺，即Vjalovognathussp.11月本文首次报道并简要描述了中国地区冈多纳周冷水相中的牙形石动物群。结果表明，冈底斯地层区可细分，西部为冈瓦周冷水相，东部为特提斯冷水相。
The Angjie Formation and Xiala Formation, present in the Shiquanhe area of Gar County in the western part of Gangdise, Tibet, belong to the Gangdise stratigraphic subregion. Conodonts have been found in the Angjie Formation, and they permit an age determination of Early to Middle Permian for that formation. The age of the Xiala Formation could be late Middle Permian. Whether the Late Permian marine deposits are present in this area still needs to be determined, but it is possible that the lower part of the Xiala Formation overlaps partly the upper part of the Angjie Formation. More importantly, the study has brought about a finding of typical peri-Gondwana cool water facies conodonts, namely,Vjalovognathussp. nov. x. This is the first report and brief description of a conodont fauna from peri-Gondowana cool water facies in China. It indicates that the Gangdise stratigraphic subregion can be subdivided; the western part belongs to peri-Gondwana cool water facies, and the eastern part belongs to Tethys.
