1980年秋,我院区域勘探室彭希龄和王智等同志在准噶尔盆地东北缘和北缘地带进行野外地质和地层工作之际,在三个泉地区原划为下第三系的红砾山组(E_1—2h)上部棕红色泥岩所夹的一层红色石英粗砂岩层中,发现了丰富的假嬉蚌属的化石。该动物群化石的发现弥补了盆地陆相上白垩统双壳类动物群化石组合序列的空白段。同时,对该区上白垩统地层的划分及古地理方面的研究有着十分重要的意义。
In the autumn of 1980, Comrades Peng Xiling and Wang Zhi from the Regional Exploration Office of our institute conducted the field geology and stratigraphy work in the northeastern margin and the northern margin of the Junggar Basin. E_1-2h) A layer of red quartz sandstone sandwiched by the upper reddish-brown mudstone has been found to have abundant fossils of Paphiopedilum. The discovery of this fossil fauna complemented the blank segment of the fossil assemblage sequence of the continental Cretaceous bivalves in the basin. At the same time, it is of great significance to study the division of Upper Cretaceous strata and paleogeography in the area.
