Investigating inter-relationships among kinematic vorticity, strain, and minimum translations from shear zones associated with internal thrusts of major fold-thrust belts

Penetrative Strain and Partitioning of Convergence‐Related Shallow Crustal Shortening, Across Scales, in the Lesser‐ and Sub‐Himalayan Thrusts: Insights From the Eastern Himalaya, Sikkim

“…The thicknesses of the thrust zones in Sikkim are much lower than the corresponding hanging wall thicknesses of the thrusts (Bhattacharyya, Mitra, & Kwon, 2015; Ghosh et al., 2020; Parui & Bhattacharyya, 2018), and most of the studied samples lie outside the thrust zones. Additionally, the published vorticity data from Sikkim indicate that the MCT and PT zones record subsimple shear that progressed from simple shear to pure shear dominated deformation (Ghosh & Bhattacharyya, 2022; Ghosh et al., 2020). Hence, ignoring simple shear will not impose significant errors in our restorations.…”
