V33D:
Redox from the Surface to the Core over Earth History III Posters

Submit an Abstract to this Session



Session ID#: 23695

Session Description:
Oxidation/reduction (redox) processes control the geochemical and geophysical evolution of Earth's core, mantle, crust, oceans, and atmosphere. The high activity of oxygen at Earth’s surface is unique among rocky planets in our solar system and is a signature of life, while the reduced nature of the interior plays a key role in volcanism and the formation of minerals like diamonds and sulfides. Redox processes have also impacted Earth differentiation and mobility of elements over deep time. This session aims to bring together a wide range of disciplines and their intersections, from the deep Earth to the biosphere. We are particularly interested in studies that promote a broad view of redox systematics and interactions between surface and interior. We invite submissions from approaches including experiments, modeling, and observations of redox processes in sediments, intrusive and extrusive volcanic rocks, exhumed metamorphic terranes, and inaccessible phase assemblages of Earth’s mantle and core.
