Volcanoes, Mush, and Mineralization with Mike Stock

About this episode

Sam Scher interviews Mike Stock about the connections between volcanic activity and ore formation.

In this episode of GeOCHemISTea , Sam talks with Mike Stock , Professor at Trinity College Dublin, about magma systems from eruption to emplacement. Drawing on work in the Galápagos and Ireland, Mike explores how the same geochemical and petrological processes govern both volcanic activity and ore formation. The conversation focuses on breaking down silos between volcanology and economic geology—highlighting shared tools, concepts, and models that are often studied in isolation. The episode closes with a discussion on batholiths and crustal-scale magma systems, offering a fresh perspective on how modern volcanology can inform interpretations of ancient intrusions and mineralized systems, making it relevant for volcanologists and economic geologists alike.
