Rajdeep Dasgupta

About

Rajdeep Dasgupta is the W. Maurice Ewing Professor of Earth Systems Science at Rice University, specializing in the formation and evolution of Earth and other rocky planetary bodies. His research investigates how interior processes influence surface chemistry and habitability, primarily through laboratory experiments and geochemical analyses, complemented by thermodynamic and other modeling approaches. His work encompasses magmatic processes in various tectonic settings, mantle melting, planetary volcanism, deep volatile cycles of Earth and other terrestrial planets, the origin of volatiles, and planetary differentiation. Dr. Dasgupta holds a B.Sc. in Geological Sciences and an M.Sc. in Applied Geology from Jadavpur University, India, and a Ph.D. in Geology from the University of Minnesota.

  Context. A magma ocean (MO) is thought to be a ubiquitous stage in the early evolution of rocky planets and exoplanets. During the lifetime of the MO, exchanges between the interior and exterior envelopes of the planet are very efficient. In particular, volatile elements that initially are contained in the solid part of the planet can be released and form a secondary outgassed atmosphere. Aims. We determine trends in the H–C–N–O–S composition and thickness of these secondary atmospheres for vary…
