IAGS x GeoHUG - Simon Griffiths

IAGS 2024

Simon takes us on a fascinating journey through his career, from his early love of geology growing up in Wales to his impressive global experiences in geochemistry and exploration. With a master’s degree in structural geology, Simon transitioned into geochemistry after discovering the potential of satellite imagery to fingerprint mineral alterations.

Geochemical Exploration in Low Sulfidation Epithermal Systems With Simon Griffiths

Geochemical exploration strategies

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.

Upscaling Pyrite Chemistry with 4-Acid Data with Aidan Kitchener

Learn about upscaling

Let’s learn about upscaling LA-ICP-MS pyrite results to whole rock geochemistry data using PCA. On the way we’ll hear about the life and times of an early career geochemist and some of the ins and outs of being a geochemical consultant. Using whole rock and in-situ pyrite chemistry to evaluate authigenic and hydrothermal controls on trace element variability in a Zn mineralised Proterozoic sub basin,

Geochemical Exploration for Greenstone Gold Deposits with Simon Griffiths

Greenstone gold exploration

For this episode we read: Archean Lode Gold Deposits in Ontario (Colvine et al., 1984) aka the Greenstone Bible. We talk about Simon’s transition from working from large mining companies to opening his own consultancy for all those considering this as part of their future. This one is dedicated to the fans of the show in Dubreuilville (Canada) who wanted some extra insight on geochemistry in greenstones

Geochemistry in the Carlin

GeOCHemISTea's first podcast ever...

For this episode we read: “The Oil-Bearing, Carlin-Type Gold Deposits of Yankee Basin, Alligator Ridge District, Nevada” (Hulen & Collister, 1999). Our chat ranges from lithogeochemistry to isotopes to pathfinder elements in the Carlin (Nevada) with Simon Griffiths. More interesting, let’s see his path from a young Welsh structural geologist to the proprietor and principal consultant of 3PXS, a UK-based economic geology and geochemistry consulting firm.

Geochemistry & High Sulfidation Epithermal Deposits with Simon Griffiths

We're talking scale...

This episode returns to our roots… to our very first episode with Simon where we talked about the geochemistry of Carlin deposits, except this time we’re talking about high sulfidation epithermal systems.
