GCA: The speciation of carbon, nitrogen, and water in magma oceans and its effect on volatile partitioning between major reservoirs of the Solar System rocky bodies

GCA: The speciation of carbon, nitrogen, and water in magma oceans and its effect on volatile partitioning between major reservoirs of the Solar System rocky bodies Damanveer S. Grewal, Rajdeep Dasgupta, Alexandra Farnell The composition of atmospheres and the resulting potential for planetary habitability in the rocky bodies of our Solar System and beyond is […]

Cambridge University Press: Origin and Early Differentiation of Carbon and Associated Life-Essential Volatile Elements on Earth

Rajdeep Dasgupta, Damanveer S. Grewal Summary This chapter reviews what is known about the fate of carbon during early differentiation of inner solar system planets. It reviews the nature of carbon fractionation in a magma ocean as compared to the core, mantle, and atmosphere, and how this may have varied between planetary bodies in the […]

GCA: The fate of nitrogen during core-mantle separation on Earth

The fate of nitrogen during core-mantle separation on Earth Damanveer S. Grewal, Rajdeep Dasgupta, Alexandra K. Holmes, Gelu Costin, Yuan Li, Kyusei Tsuno Nitrogen, the most dominant constituent of Earth’s atmosphere, is critical for the habitability and existence of life on our planet. However, its distribution between Earth’s major reservoirs, which must be largely influenced […]

Science Advances: Delivery of carbon, nitrogen, and sulfur to the silicate Earth by a giant impact

Delivery of carbon, nitrogen, and sulfur to the silicate Earth by a giant impact Damanveer S. Grewal, Rajdeep Dasgupta, Chenguang Sun, Kyusei Tsuno and Gelu Costin Earth’s status as the only life-sustaining planet is a result of the timing and delivery mechanism of carbon (C), nitrogen (N), sulfur (S), and hydrogen (H). On the basis of their isotopic signatures, terrestrial […]
