Recognition of tuffs in the middle-upper Dingqinghu Fm., Lunpola Basin, central Tibetan Plateau: Constraints on stratigraphic age and implications for paleoclimate

The Lunpola Basin plays a key role in determining the elevation history of the central Tibetan Plateau, which is closely related to uplift dynamics and paleoclimatic evolution. However, accurate age constraints on the basin stratigraphy reflecting tectonic, paleo-elevation and climate information have long been vigorously debated, mostly due to a lack of absolute age controls. Here, we found two altered tuff layers in the middle-upper Dingqinghu...
