Multidisciplinary Approaches to Understanding the Differentiation and Evolution of Earth and other Planetary Bodies
Session ID#: 85067
Session Description:
In order to understand planetary evolution, we must understand the processes by which rocky planetary bodies differentiated into a core, mantle, and crust. This differentiation influenced subsequent planetary-scale physical and geological events as well as formation of chemical reservoirs. While recent analytical developments have led to high-precision isotope analyses that are revolutionizing our understanding of these processes, identifying planetary building blocks and unraveling how differentiation occurred remains unclear. This session aims to integrate expertise from various fields of research within the overarching field of planetary sciences to answer big picture questions about the differentiation and evolution of planetesimals and rocky planets. Related processes include accretion, core segregation, mantle crystallization and overturn, late accretion, the Moon-forming events, and crust formation/destruction. We encourage submissions combining cutting-edge isotope ratio analyses (stable or radiogenic) of cosmo- or geo-chemical materials, petrology, geodynamical modelling, seismology, or experimental petrology.
