The dynamics, evolution and life of the early Earth is still a widely debated topic with many uncertainties. This interdisciplinary session aims at studying the various aspects of early Earth, both observational and modeling studies. Typical questions to be answered relate to: Earth’s accretion and differentiation; core formation; initiation of the geodynamo; inner core growth; growth and stabilization of continents; formation of crust; thermal structure of and the style of convection in the mantle; viability and observations of modern-style plate tectonics with subduction, and of alternative tectonic mechanisms; Earth’s earliest life; importance of mantle plumes through time. We welcome all contributions that discuss geochemical, geophysical, geological and biological processes that relate to the aforementioned topics.

Invited presenters:
- Nicolas Flament - University of Sydney, Australia
- Henri Samuel - University of Bayreuth, Germany
- Nora Noffke - Old Dominion University, Virginia, USA
