My research interests include:
- Tectonics and crustal evolution of various shear /suture zones and crustal blocks.
- Archean tectonics and TTG genesis, petrogenesis and metamorphic history of various crustal domains.
- Interaction between Earth crustal and surface processes.
- Paleogeography of Eastern Gondwana, focusing on Madagascar-India-Sri Lanka-Antarctica correlation.
My current study areas include:
- Southern granulite terrain, India
- Dharwar craton, southern India.
- Himalaya, northern India
- Madagascar and Sri Lanka
My research includes multidisciplinary approach:
- Image based studies (mapping, remote sensing and GIS),
- Field studies (structural, lithological information and field relations, sample collection)
- Laboratory studies (petrological, mineral chemical, geochemical, geochronological and isotopic studies).
- Integration of other studies with my results (e.g. geophysical and sedimentological results).
Evolution of the Palghat-Cauvery Shear Zone in southern India: Implications on the Tectonics and Paleogeography of eastern Gondwana
(Initiation Grant, IIT Kanpur, 2018-2020)
Palghat-Cauvery Shear Zone in southern India is considered as a major terrane boundary. However several controversies exists regarding the position, origin, evolution, age and extension of this shear zone. The project aims to address these topics by using a multidisciplinary approach involving integration of remote sensing, field, petrological and geochronological methods.
