| 中文摘要:为在我国西部寻找新的战略性的石油地质储量按替区，我们在西藏措勒盆地开展了为期３年（１９９５～１９９７）的石油地质综合研究，在它日错地区首次发现了昂杰组地层，昂杰组自创建以来一直被置于上石炭统＾〖１〗，根据新获得的化石资料及区域地层对比分析结果，我们将该组于下一叠统。区内昂杰组的发现对于准确确定该组的时代归属、重新认识夏岗江雪山地区“坚扎弄组”及完善冈底斯－念青唐古地层区古生界界序具有重要意义。 |

| Abstract:The authors carried out petroleum geological integrated research in Cuoqin basin of Tibet for three years (1995～1997) in order to search for new strategic petroleum reserves in western China. Angjie Formation was first found in Taricuo area. The Angjie Formation has been all along assigned to Upper Carboniferous since its naming.The authors now assign the formation to Lower Permian in accordance with new data of fossils and stratigraphic correlation. The discovery of Angjie Formation is of great significance in the confirmation of the age of this formation and the Jianzhalong Formation in Xiagangjiang Mountian and the perfection of the Paleozoic stratigraphic sequence in Gangdise-Nyainqentangtha region. |
