Dear Colleagues, We kindly invite you to submit abstracts to our session at Goldschmidt 2026 in Montreal: *Session 11a: Geochemical lenses into the environmental legacies and futures of energy and mineral resources* As we navigate the global energy transition, understanding the geochemical fingerprints of both legacy fossil fuel infrastructure and emerging critical mineral extraction has never been more important. This session brings together field, laboratory, and/or modeling studies examining how energy and mineral resource use affects environmental quality and human health. We welcome contributions on: - Contaminant distribution across temporal and spatial scales - Geochemical signatures and tracers for source identification - Processes governing mobility, transformation, and fate of contaminants - Links between contaminant geochemistry and health risks - Policy-relevant science for environmental protection and resource management *Abstract deadline: February 26, 2026* *Submit here:* https://conf.goldschmidt.info/goldschmidt/2026/meetingapp.cgi/Session/9058 Please share with colleagues and students who might be interested! Best regards, Rachel Coyte + Zhen Wang
