Hello everyone,

We invite your attention to the session
"DI016 : Planetary accretion, core formation, and magma oceans in the inner Solar System"
at the AGU fall meeting 2021 from 13-17 December 2021 in New Orleans. Authors will be able to present in-person or online.

The session focuses on the physics and chemistry of the formation and early evolution of the Earth.

To submit your abstract:

Deadline for abstract submission: August 4th, 2021.

Session details:

Confirmed invited speakers: Dr. Francis Nimmo, professor @ UC Santa Cruz | Dr. Laetitia Alibert, postdoc @ Museum für Naturkunde


Session description:
The accretion and primordial differentiation of the terrestrial planets set the initial conditions for the evolution of their cores and mantles. Geochemical and isotopic observations alongside experiments constrain the timescales and conditions of planet formation. However, to interpret these observations, we must understand physical processes over a wide range of time and length scales, from centimeter-scale chemical transfers and giant collisions at the planetary scale, up to large-scale transport and planetary migration within the solar protoplanetary disk. Thanks to advances in sample analysis, experiments, and modelling, integrated models of planetary accretion and differentiation have recently emerged. For this interdisciplinary session we invite contributions from (isotope) geo- and cosmochemistry, geochronology, fluid dynamics, and astrophysics that address the accretion and earliest differentiation of the rocky planets, including core formation and metal-silicate equilibration, the role of (giant) impacts, pebble accretion, magma oceans, preservation and significance of primordial heterogeneities, lunar origin, and late accretion.
