在1∶25万岔路口幅区调红山湖一带地质填图和实测地层剖面中,于西昆仑北羌塘陆块岔路口地区原划上石炭统恰提尔群中采到了大量珊瑚、蜓类化石,经鉴定其形成时代为早二叠世晚期—中二叠世早期。该生物化石的取得,为该套地层时代划分提供了依据,填补了西昆仑北羌塘陆块岔路口地区缺失早—中二叠世地层的空白,为进一步详细研究西昆仑北羌塘陆块地层层序格架及地质演化,提供了新的基础资料。
In the 1: 25 000 fork range area of Hongshan Lake geological mapping and measured stratigraphic cross section, in the West Kunlun North Qiangtang land fork junction area originally planted in the Upper Carboniferous Qiarter group to get a lot of coral, dragonfly Fossils, identified as the formation of the Early Early Permian - Early Middle Permian. The acquisition of this fossil fossil provided the basis for the stratigraphic division of this set of strata and filled up the blank of the missing Early-Middle Permian strata at the junction block of the North Qiangtang in Western Kunlun. In order to further study the northern Qiangtang block Stratigraphic sequence framework and geological evolution, providing a new basic information.
