The formation and early evolution of the Earth and the Moon
Session ID#: 161851
Session Description:
The binary nature of Earth and the Moon is in many aspects unique in the solar system, including the breathable atmosphere, biodiversity, and plate tectonics on Earth, and the anomalously large size of the Moon. It is thought that the Moon-forming giant impact was the last major accretion event for the proto-Earth, and thus set the initial condition for the 4.5 billion years’ evolution of the Earth-Moon system. However, many aspects of the physical and chemical state of the early Earth and Moon after the giant impact are poorly constrained, owing to the erased signatures at Earth’s surface due to plate tectonics and limited accessibility of lunar samples. Yet, the ancient lunar geological record and the many primordial signatures and ancient structures of Earth’s deep mantle may together provide invaluable insights into the earliest dynamics of the Moon and Earth, how the Earth-Moon system evolved, and why life thrived on our home planet. We invite contributions from a wide range of disciplines including, but not limited to, astrophysics, planetary science, petrology, lunar geoscience, geochemistry, geodynamics, and geophysics, and using observational, experimental, numerical, and/or theoretical approaches.
