Dear Colleagues, We encourage you to submit abstracts to the session “Trace elements trace processes: Using mineral chemistry to track geologic change in igneous, metamorphic, and sedimentary systems” at the 2026 GSA Connects Meeting in Denver, CO, October 11-14th. We welcome abstracts from a broad range of studies that use mineral chemistry, particularly trace elements, to address geologic problems. Session Description: Mineral chemistry, zoning textures, and petrochronology record evolving geologic conditions. This session highlights how mineral chemistry tracks the evolution of igneous, metamorphic, and sedimentary processes, including magma evolution, source fingerprinting, fluid-rock reactions, and crustal evolution. Invited Speakers: Priscilla Martinez (University of Arizona) Peter Lindquist (University of Washington) Abstract Deadline: 6 August 2026 https://gsameetings.secure-platform.com/connects26/organizations/main/home We hope to see you in Denver! Best, Session Conveners: Maddie Lewis, Sarah George, Margo Odlum, Amy Moser, Eirini Poulaki ------------------------------------------------------------------------ Dr. Madeline Janine Lewis (she/her) Assistant Professor Department of Geology and Geophysics University of Wyoming Email: mlewis48@uwyo.edu
