Opposite shear senses: Geneses, global occurrences, numerical simulations and a case study from the Indian western Himalaya
D Dutta, S Mukherjee - Journal of Structural Geology, 2019 - Elsevier
Opposite shear sense (OSS) is manifested by the presence of conflicting shear sense

Review of major shale-dominated detachment and thrust characteristics in the diagenetic zone: Part II, rock mechanics and microscopic scale
Characterising large shale thrust zone behaviour down to the diagenetic-metamorphic
boundary is both simple and complex. The task in critical taper, analogue and numerical …

In situ observations on the coupling between hydraulic diffusivity and displacements during fault reactivation in shales
Key questions in fault reactivation in shales relate to the potential for enhanced fluid
transport through previously low‐permeability aseismic formations. Here we explore the …
