This age apparently dates initial reactivation of the northern Tian Shan in response to the India-Asia collision, which continues to raise the mountain range today. Numerous studies of the Himalaya and Tibet suggest that a major shift from extrusion-dominated to crustal thickening-dominated tectonics occurred in latest Oligocene-early Miocene time, approximately coincident with the start of unroofing in the Tian Shan. This suggests that Tian Shan unroofing was a distant effect of that shift within the collision zone. This content is PDF only. Please click on the PDF icon to access.
