摘要
Based on regional geological and stratigraphic analysis, an event stratigraphic framework of Eocene-Miocene in the Qaidam Basin has been established. Five types of event stratigraphic surface, eight event stratigraphic zones, six event stratigraphic associations, and one event stratigraphic assemblage have been recognized. Because of continental collision between India and Eurasian, Tibetan plateau uplift and a series of Himalayan movement resulted in the development of the Eocene-Miocene event stratigraphic assemblage in western Qaidam Basin.
