P11A:
Accretion, Differentiation, and Early Planetary Evolution I Posters
Session ID#: 7926
Session Description:
The early planetary evolution is punctuated by major events such as accretion and core formation. These involve a variety of physical and chemical processes interacting over a very large range of scales in space and time. Understanding these earliest stages is fundamental in order to constrain the subsequent billions of years of thermo-chemical evolution of terrestrial bodies. Due to vigorous internal dynamics and to their size, the largest terrestrial objects have undergone one or several episodes of global melting, which complicates the reconstruction of their early histories. However, smaller objects may have retained frozen traces of their early evolution, thus providing a unique opportunity to test model predictions against observations. We welcome contributions from fluid dynamics, geochemistry, astrophysics, mineral physics, geology and petrology that address the early formation and evolution of planetary objects ranging from meteorites to Earth-sized planets.
