Early Earth Evolution throughout the Hadean and Archean
Session ID#: 252562
Session Description:
Deciphering the differentiation and evolution of the early Earth is critical to elucidating its origins, chemical structure, and processes that led to the emergence of the earliest crust, tectonic processes, and conditions for life. Such information is encoded in the Archean and Hadean rock records and zircons, and the analysis and study of early materials are important for obtaining constraints on the origins of the planet, initiation of crustal growth, interactions between the hydrosphere and atmosphere with the crust and mantle, and underlying geodynamic processes. This session welcomes contributions from modeling, measurements, field observations, and experiments from geology, geochemistry, geochronology, paleomagnetism, mineralogy, and petrology. Topics of interest include crust-mantle differentiation, magma oceans, interactions between the atmosphere and hydrosphere and solid Earth processes, initiation of plate tectonics, and insights into planetary origins. Our session welcomes novel and innovative approaches, as well as interdisciplinary collaborations that synthesize insights from various fields.
