Hi Everyone (and apologies for cross-posting), We’d like to invite submissions to session T134: The Importance of Petrology, Volcanology, and Geochemistry to Issues of Societal Relevance, at GSA Connects 2025 in San Antonio. We hope that this session will attract important, impactful, and societally relevant submissions that highlight the importance of our field in furthering our understanding of planetary bodies, expanding energy resources, deciphering and reducing the impact of geological hazards, and addressing key environmental challenges. Igneous and metamorphic petrology, volcanology, and high-temperature geochemistry play fundamental roles in addressing some of society’s most pressing challenges; however, these contributions are sometimes underrecognized. These disciplines are key to understanding and mitigating natural hazards, ensuring sustainable access to critical minerals, unraveling the deep Earth processes that shape our planet, and educating the broader public about the geosciences. For example, research in subduction zones reveals volatile cycling and deep carbon storage, directly informing climate models and long-term carbon sequestration strategies. Similarly, research on past magmatic, volcanic, and metamorphic events provides key insights into earthquake generation, crustal deformation, and seismic hazard assessment—essential knowledge for communities living in tectonically active regions. Studies of fluid-rock interactions inform strategies for mitigating environmental contamination, while the study of planetary magmatism helps us understand Earth’s place in the solar system. From volcanic hazard forecasting to securing the mineral supply chains essential for a green energy transition, the impact of petrology and geochemistry extends far beyond the lab and into global policy, industry, and environmental sustainability. As demand for sustainable resources and hazard mitigation strategies grows, fundamental research in petrology and geochemistry is essential for addressing global challenges. This session celebrates the critical importance of these fields and aims to highlight their wide-ranging applications, ensuring their value is fully recognized by both new and experienced geoscientists alike. We invite contributions showcasing the far-reaching global and societal impacts of petrology and geochemistry, highlighting how high-temperature Earth processes shape dynamic systems and intersect with policy, industry, resource exploration, seismic potential, natural hazard mitigation, planetary evolution, long-term climate change, environmental sustainability, and public-facing science outreach and communication. By bringing these essential connections to the forefront, we aim to inspire both seasoned researchers and new geoscientists to recognize and advocate for the indispensable role of petrology and geochemistry in shaping our world. Our invited speakers are Laura Waters (NM Tech) and Anne Haws (Yale).
