| 摘 要： | 通过西昆仑大红柳滩一带地质填图和实测地层剖面,从原划上三叠统克勒青河群中采到了大量孢粉和珊蝴、菊石类等化石,经鉴定其形成时代主体为二叠纪,经区域地层对比,重新厘定为二叠纪黄羊岭群。该生物化石的取得,为分析研究西昆仑微陆块及巴颜喀拉晚古生代—中生代边缘裂陷盆地的地质构造演化,提供了新资料。

| Abstract: | In geological survey and measuring formation profiles conducted in Dahongliutan area,West Kunlun,a large number of fossils such as sporopollen and coral,ammonoid,etc.have been found in the former attributed Triassic Keleqinghe Group.It is identified that the age of its formation is mainly in the Permian and based on regional stratigraphical correlation,they are redefined as the Permian Huangyangling Group.The acquisition of the fossils provides new data for analysis and study of the tectonic evolution of the West Kunlun microcontinent block and the Bayankara late Paleo-Mesozoic marginal rifting basin. |
