This session will explore how direct observations from the rock record, insights from theoretical models, experimental results and phase equilibria modeling can be used to provide constraints on the origin and evolution of the Earth's crust and the physical and chemical conditions imparted by the crust that constrained the development of life. We welcome contributions that may address the following issues: geodynamic conditions for the formation and recycling of primary crust through time; the tectonic setting and rates of formation, recycling and destruction of the continental crust through time; and, the relationship between melt production and ocean/atmospheric development. Also welcomed are studies that use the crust as a paradigm to search for evidence of early life and constrain the nature of near surface environments.
