Abstract
Geological observation in the eastern end of the Himalaya shows that the Asia/India Suture is folded. Metamorphic rocks derived from India occur structurally below the suture, in the core of a regional antiform. Isotopic and fission track dating establish cooling‐exhumation of rocks from c.30 km depth within the last 4 Myr. We argue that exhumation is caused by ∼ 10 mm yr‐1 erosion coeval with crustal scale folding.Keywords
