Every geoscientist is capable of understanding and applying geochemical data, however, at GeocHemiSTea we understand that there is an incredible amount of nuance and accumulated knowledge. We are here to break down the impediments towards geoscientists learning more about this exciting field! Are you a student wanting to break into the field? Listen to each episode to see how reknown geochemists got to where they are today. Are you intrigued by integrating geochemistry, but don't know how? Stay tuned! Lastly are you looking for some Tea/good gossip? We got it.

Geochemical exploration in low sulfidation epithermal systems with Simon Griffiths

This month on GeOCHemISTea, we welcome back Simon Griffiths, Principal Consultant at Third Planet Exploration Services, to unpack the geochemical exploration strategies for low-sulfidation epithermal systems. From vein textures to vanadium-rich roscoelite halos, Simon walks us through practical strategies for geochemical targeting and alteration mapping. He shares insights into sampling, spectral workflows, and how roscoelite at Porgera became one of the most reliable vectors to high-grade gold. Plus a wild tale about how an ICP machine was used to crack down on gold theft in the mine lab.

For this episode we read:Geology of the Porgera Gold Deposit, Papua New Guinea (Hay et al., 2020)
