Title: Outward and upward growth of north-central Tibet: Constraining mechanisms that build high elevation, low relief plateaus
Quantitative constraints of paleoelevation of large orogenic belts and plateaus shed light on continental dynamics and the influence of tectonics on regional to global climate change. The surface uplift history of the Hoh Xil Basin in north-central Tibet is yet poorly constrained.
This study reports both carbonate formation temperatures and depositional ages to explore paleoelevation history. We provide the first quantitative evidence of a long-hypothesized early–middle Miocene phase of surface uplift of 1.0 ± 0.7 km in the Hoh Xil Basin. Results of this study demonstrate the significance of sub-surface geodynamic processes, i.e., convective removal, crustal flow, and magmatic inflation, in driving localized surface uplift and flattening of plateau surface during the late stage of large orogenic plateau formation.
