New Petrological and Sedimentary Evidences on the Late Cretaceous Uplift of the Tibetan Plateau

The India-Asia collision and uplift of the Tibetan plateau are the most important geological events in Earth＇s history; it profoundly affects our understanding of global climate change during the Cenozoic. Despite a research history over half a century, the uplifting history remains hotly controversial. The early uplifting model suggested that the Lhasa terrane attained an elevation of 3-4 km at -99 Ma due to the Lhasa-Qiangtang collision. However, the evidences are mainly from deformation of the Lhasa terrane and inconsistency with the palaeontological data.

Geochronological and Geochemical Evidence for the Sedimentary Transformation from the Banxi Period to Nanhua Glacial Period

Objective There has been considerable debate about the definition of the lower boundary of Nanhua System by far.One definition is based on sedimentary sequence of different stages of basin evolution,focusing on whether deposits of the Banxi Period should be classified as Nanhua System.Another is the onset time of Nanhua glacial period.
