Research interests

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).

 

Research Projects

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.
