Abstract

Abstract Potassic volcanism has been widespread and semi-continuous on the Tibetan plateau since ∼13 Ma, post-dating the orogenic thickening of the India-Asia collision. Volcanism may have commenced slightly earlier (∼16–20 Ma) in the southern portion of the plateau and then ceased around 10 Ma. The...
