New Publication: (June 2020) Li et al. Tectonics, Oligocene deformation of the Chuandian terrane in the SE margin of the Tibetan Plateau related to the extrusion of Indochina

This new publication, available in Tectonics, provides a revised chronostratigraphy for Lühe Basin. This revised chronostratigraphy provides additional evidence to support the theory that many of the "Neogene" sedimentary basins in the SE margin of Tibet being older than had been previously thought. Ar-Ar ages from volcanic ashes and new magnetostratigraphic data constrain sedimentation in the Lühe Basin to between ~35 and 26.5 Ma

Key Points
1. We revised the Lühe Basin sedimentation from late Miocene to 35-26.5 Ma by magnetostratigraphy and 40Ar/39Ar chronology;
2. Oligocene uplift of the SE Tibet margin is related to the extrusion and clockwise rotation of Indochina;
3. A reassessment on the age of other late Cenozoic basins in SE Tibet margin is required.
