Professor Bernard Marty will deliver the 5th annual Lobanov-Rostovsky Lecture in Planetary Geology.

Abstract: Understanding the origin and evolution of life-supporting volatile elements (water, carbon, nitrogen) on Earth is an evolving and debated area of research. Stable isotope ratios suggest that volatiles were primarily sourced by planetary bodies from the inner solar system.

However, recent measurements by the European Space Agency Rosetta probe on the coma of Comet 67P/Churyumov-Gerasimenko indicate that comets also contributed volatiles to the surface of our planet. Using this data together with recent high-precision analyses of noble gases from the deep mantle, we shall discuss the sources of volatile elements and the timing of their delivery to the proto-Earth.

The lecture will be followed by a drinks reception, to which all attendees are welcome. Please sign up via Eventbrite so we can cater accordingly.
