Tectonic Control Over Shallow Crustal Exhumation Across the India‐Asia Convergent Margin

Abstract

Exhumation is the manifestation of the interactions between tectonics and climate, and it plays an essential role in understanding the landscape and structural evolution of mountain belts (e.g., Beaumont et al., 1992;Whipple, 2009). Previous research suggests that asymmetrical exhumation rates occur in collisional orogens, with exhumation maxima occurring in either the fold and thrust belts or in areas with maximum precipitation in the orogenic wedge (Whipple, 2009;Willett, 1999). In contrast, plateaus in orogenic belts' interiors are characterized by slowly eroding landscapes that constitute the internally drained basins in the contractional tectonic settings (

“…W. Wobus, Hodges, & Whipple, 2003). However, kinematic or tectonic control over erosion and landscape evolution with the demonstration of the decoupling of precipitation and erosion has also been equally argued (Adlakha et al, 2019;Adlakha, Lang, Patel, Lal, & Huntington, 2013;Coutand et al, 2014;Godard et al, 2014;Jain, Kumar, Singh, Kumar, & Lal, 2000;Landry, Coutand, Whipp Jr, Grujic, & Hourigan, 2016;Patel et al, 2011;Pebam et al, 2021;Pundir, Adlakha, Devrani, & Kumar, 2021;Robert, Van der Beek, Braun, Perry, & Mugnier, 2011). In the present case, we observe the rapid exhumation in the eastern LPC, which lies in the low-precipitation zone (Figure 9e) that clearly suggests that tectonics is a prime driver of exhumation in this region.…”
