Dyuti

Dyuti Prakash Sarkar is an Assistant Professor (since 2025) in the Department of Geosphere Sciences, Yamaguchi University. A structural geologist at heart, he works on rock deformation across three themes: Himalayan fault zones and crustal deformation; fabric development in petit-spot mantle xenoliths and how the oceanic lithosphere deforms; and rotary-shear experiments, from gouge to rock-on-rock samples, probing how earthquakes nucleate. Originally from Kolkata, he completed his PhD at Hiroshima University in 2020 and has been based in Japan since then. Outside the lab he's usually behind a camera, hiking the local hills, or enjoying an espresso in an offbeat café.

From Fault Architecture to Grain-Scale Deformation: Integrating Field, Microstructural, and Experimental Approaches

Fault zones are far more complex than the lines we draw on geological maps. Their internal structures, mineralogical compositions, and deformation histories offer important clues to deformation mechanisms and even how earthquakes might occur. But how can we connect what we observe in the field with the microscopic processes and mechanical behaviour of faults at …[Read More]
