Colleagues, Please consider submitting an abstract to Goldschmidt 2024 session 3g: "Formation of evolved crust on Earth and other planets". Abstract deadline is March 29. We invite contributions from all aspects related to crustal evolution from the perspective of igneous, metamorphic and weathering processes and from all approaches (field, mineralogy, geochronology, geochemistry, laboratory, modeling, big data, small data, and more). Invited Speakers: Claire Bucholz (Caltech), Xu Chu (University of Toronto) https://conf.goldschmidt.info/goldschmidt/2024/goldschmidt/2024/meetingapp.cgi/Session/6420 See you in Chicago! Chris Yakymchuk (U Waterloo) Ming Tang (PKU) Session 3g: Crust forms as an outcome of terminal planetary differentiation. On Earth, unique differentiation processes have led to the formation of abundant evolved crust. This crust offers a rich record of Earth’s complex tectonic history and also acts as an important boundary layer that controls mass and energy exchange between Earth’s surface and mantle. These processes have profoundly shaped Earth’s surface environment and altered the physiochemical properties of Earth’s interior. However, we have a limited understanding of the formation, differentiation, and stabilization of the Earth’s crust, including rarely exposed deep crust that immediately overlies the mantle. Furthermore, sporadic formation of evolved crust has also been documented on extraterrestrial planets over the last several decades, adding a new dimension to our understanding of planetary crust evolution. This session welcomes abstracts related to the crustal igneous, metamorphic, and weathering processes on Earth and beyond.
