description Rajdeep Dasgupta Overview
Rajdeep Dasgupta is a geoscientist and professor at Rice University whose research focuses on experimental petrology and the geochemistry of Earth's interior. His work uses high-pressure laboratory experiments to investigate the behavior of carbon and other volatiles in the mantle, contributing to understanding of the deep carbon cycle. He has published on topics including mantle melting, magma formation, and the role of carbon in planetary processes.
help Rajdeep Dasgupta FAQ
What does Rajdeep Dasgupta study about carbon inside Earth?
Dasgupta investigates how carbon is stored, transported, and melted within Earth's mantle. His group at Rice University recreates mantle conditions with high-pressure and high-temperature experiments rather than observing those depths directly.
How can laboratory experiments reproduce conditions in the mantle?
Experimental petrologists compress tiny rock and mineral samples in devices such as piston-cylinder and multi-anvil presses, then heat them to mantle-like temperatures. The resulting phases and melts reveal how elements behave far below Earth's surface.
Why is Dasgupta's research relevant to Earth's habitability?
Carbon, hydrogen, sulfur, and other volatiles influence volcanism, atmospheric composition, and long-term planetary climate. Studying their movement between the mantle and surface helps explain how a rocky planet develops habitable conditions.
Does Rajdeep Dasgupta study planets other than Earth?
Yes, his experimental geochemistry also informs models of planetary differentiation and rocky worlds. The same high-pressure methods can test how cores, mantles, melts, and volatile inventories may have evolved on early Earth and other terrestrial planets.
