A big thanks to Heidi Pass, Michelle Carery, Dave Lawie, Pim van Geffen, Putra Sadikin, Mike Whitbread, Des Pascoe, & Steve Sugden for rolling with this as we tried for our Holiday special to embody the Dickens-esq theme of Geochemistry: Past, Present & Future.
We always talk about fluids in geochemistry. How the ore metals are moving and how they are depositing – we think in pressure-temperature-redox space. However, when we get our geology, structure and geochemistry in 3D… and then we start to rotate a model for the first time… it is the most rewarding moment because we
here are geochemists and isotope geochemists… this episode we’re speaking with the latter and this discussion could not be more interesting! Seriously. I found myself at different points so riveted (by that I mean thinking too hard) that I forgot I was supposed to be asking more questions.

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.
This is a different conversation from those we’ve had before because we took two extremely different topics in hydrogeochemistry and pXRF on drillcore and looked at how these different techniques and scales come together in a junior exploration program.
A favorite thing Dave likes to say is “we do all sorts of things to the rocks… to try and understand them….” But then Dave often likes to tell geologists and especially mining engineers that “rocks don’t give a shit to what we think of them. They’re just rocks. They’re just gonna sit there and be like, all right, whatever guys. I’m a rock.”
Perhaps more interesting that the foundation of Datarock is built on Aussie rules football is some of the advice that Brenton Crawford, one of the the company’s founders has to impart: that we can get distracted by what we ‘need’ from a university in order to get the geoscience job we want. He goes on
For those who’ve asked “how do I become an environmental geochemist?
We think we speak for everyone that the geochemical community is forever enriched by Putra’s decision not to study plankton biostratigraphy or go into construction.
