We would like to draw your attention on the session 2f at the Goldschmidt Conference that will be held in Paris from 13 to 18 of August 2017.
02f: Mars – Early Differentiation and Dynamic Evolution
Convenors: David Baratoux, Vinciane Debaille
Keynote: Doris Breuer (DLR)
Geochemical and numerical models suggest that Mars evolved very rapidly after its formation with core segregation, mantle differentiation and crust formation following shortly after the planet’s initial accretion. This layered structure of crust, mantle and core, likely formed through an early magma ocean stage but was later modified by subsequent partial melting, crustal growth and differentiation. Isotopic variations in Martian meteorites (e.g. in 142Nd 182W) suggest the early formation of chemical heterogeneities in the mantle and their preservation until today. When and how did these reservoirs form and how could they survive to the present day? What were the major events affecting the chemistry of Mars and interior dynamics? What can be learned from studies of surface material and meteorites that document the major, trace and volatile element composition of magmas and fluids, the thermodynamic conditions (fO2, temperature, pressure) and timing of magmatic events? This session welcomes contributions based on remote sensing and Space mission observations, numerical models, in-situ or laboratory analyses and experimental data that explore the formation and evolution of chemical heterogeneities created in the early history of Mars and the subsequent dynamical and chemical evolution of this planet.
Abstract submission deadline is April 1st 2017 (23:59 CET). Please do not hesitate to forward this e-mail to your team.
We are looking forward to seeing you in Paris.
