Project description
A closer look at the formation and evolution of terrestrial planets
New cutting-edge stable isotope systems will be used to study the accretion and differentiation processes that have shaped the present composition of Earth as well as the moon and Mars. These new systems will be developed by the EU-funded METAL project and used to constrain the origin of the solar system’s volatile element depletion. The project will also quantify the isotopic effects during metal/silicate partitioning and evaporation in all conditions relevant to planetary accretion and differentiation. Another aim is to build a physical model of volatile loss and to study the timing, proportions, fate and nature of the material that accreted to Earth and Mars after core formation. The findings will boost our understanding of the formation and early evolution of terrestrial planets.
Objective
Understanding the formation and early evolution of terrestrial planets is one of the most important goals in sciences. The objectives of this proposal, METAL (Making tErresTriA pLanets), are to study the accretion and differentiation processes that have shaped the present composition of the Earth, Moon, Mars and differentiated asteroids including understanding the origin, and timing of delivery of their volatile and siderophile elements. To reach this goal we have identified the best-suited isotopic tools, which are sensitive to the different physico-chemical processes acting at different stages of planetary formation. This work will involve: 1) Development and use of new cutting-edge stable isotope systems for moderately volatile elements (e.g. In, Sb, Sn) in terrestrial, lunar and meteoritic materials, in order to constrain the origin of solar system’s volatile element depletion. 2) Quantifying experimentally the isotopic effects during metal/silicate partitioning and evaporation in all conditions relevant to planetary accretion and differentiation. 3) Building a physical model of volatile loss. 4) Studying the timing, proportions, fate and nature of the material that accreted to Earth and Mars after core formation (i.e. the late-veneer) by using a new method based on the stable isotopes of a highly siderophile element, Pt. This high-risk high-rewards approach seeks to link innovative novel isotopic systems, experiments under extreme conditions, and dynamical modelling, to solve long-standing major scientific questions related to the formation and evolution of the terrestrial planets.
