Building Life Long Conversations through Geochemistry.

Want to learn more about geochemistry and geochemists? You are in the right place. GeOCHemISTea is a monthly podcast where geoscientists talk through a geochemistry topic they genuinely care about, anchored by a paper or two and grounded in real experience.

GeOCHemISTea and changing geochemistry

Each episode is designed to make geochemical thinking more accessible, whether you are early-career, mid-career, research-focused or using geochemistry in exploration and mining workflows.

This podcast is free of vested interest. Opinions are those of the host and the guest.
