In this episode of GeOCHemISTea, Sam sits down with Gabe Bowen to explore the world of forensic isotope geochemistry and the power of isoscapes.
This episode of GeOCHemISTea explores cobalt cycling, critical metals, and why geochemists need to think beyond bulk chemistry to understand how elements behave in surface environments.
Simon Bolster joins GeOCHemISTea to unpack what actuallymakes near-surface geochemistry work in mineral exploration: understanding regolith and landforms before you ever “put dirt in bags.” With four decades in gold exploration, Simon argues that many programs fail not because geochemistry is “bad,” but because sampling and analytical choices do not match the terrain,the cover, or
This episode discusses how artificial intelligence is transforming research and education, exploring practical applications, opportunities and challenges across academic and scientific fields.
In this episode of GeOCHemISTea, Sam talks with Mike Stock, Professor at Trinity College Dublin, about magma systems from eruption to emplacement.
This month on GeOCHemISTea, Sam sits down with Scott Halley to talk about extracting meaningful mineralogy from standard four-acid assay data.
Alecos Demetriades, applied geochemist and Chair of the IUGS Commission on Global Geochemical Baselines (2024–2028)
Simon Griffiths breaks down geochemical strategies for low-sulfidation epithermal systems, roscoelite vectors, sampling workflows, and real-world exploration lessons from Porgera.
Hugh De Souza traces gold analysis evolution from fire assay to photon assay, sharing lab experience, physics insights, and perspectives.
Mary Doherty discusses stream sediment geochemistry fundamentals, evolving methods, QA/QC, and how modern tools shape effective mineral exploration workflows.
