Abstract:
The West Kunlun Mountains is in the region of cold climate and thin free oxygen, where natural and traffic condition are poor, geological survey and field work are difficult, therefore, the research level on regional geology is preliminary, reliable microfossil evidence has not been obtained from the Wenquangou Group. After the geological survey and research, quite abundant acritarchs and chitinozoans, such as: Leiosphaeridia, Florisphaeridium, Conochitina, Ancyrochitina, Desmochitina, Eisenackitina, Rhabdochitina, Cyathochitina, Lagenochitina and Eremochitina were found in the Wenquangou Group. It provides important micropaleontological evidence for ascertaining the age of epimetamorphism clastic rocks of the lower-middle parts of the Wenquangou Group, in the West Kunlun region.
