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. Support this podcast: https://podcasters.spotify.com/pod/show/geochemistea/support

Geochemistry, nature's gift to mine closure with Rob Bowell
For this episode we read Rob's paper: Natural attenuation in the vadose zone: Nature's gift to mine closure (Bowell, 2023)
From rethinking the green economy to recovering metals and ores in naturally occurring ways, this episode encompasses a lot of topics currently in the news but a uniquely Rob perspective.
Along the way, we may even learn about the vadose zone and the potential to remediate sites naturally.

Outtakes with Rob Bowell
Want to hear some more of Rob's thoughts? But also just general silliness from before we started to record? Enjoy!

Sensor and method selection with Ben Chi
At GeOCHemISTea we love it when someone is so passionate about their geochemistry topic that they reach out and request(!!) to be on the show. An honor, Ben!
So what ground did we cover... manifest your own destiny (or was that the US in the 1800s?). Ben has been a geochemist, a geophysicist, and a data scientist; there's lots of nuggets in there for young geos who are looking for the how-to... so how did Ben become a geochemist?
Our topic of interest this month was to talk about methodology selection to solve geochemical, geometallurgical, and dare I say geophysical situations that arise during the course of exploration and mining programs... and dare I say... Ben has a lot of opinions, advice and ideas on the matter!
For this episode we read:
Characterization of Ore Properties for Geometallurgy (Butcher et al., 2023)

Head in the Clouds, Feet in the Data with Britt Bluemel
For this episode we read:
Using machine learning to estimate a key missing geochemical variable in mining exploration: application of the Random Forest algorithm to multi-sensor core logging data (Schnitzler et al., 2019)
A big difference between applied geochemistry and machine is the terminology, but once you start to chip away at this, like Britt, you will realize that the two disciplines are not so different.
Join us as we talk about dimensionality reductions, transformations, and workflows pre- and post- her introduction to the realm of data science. And talk about a really neat paper that used random forest to predict sodium for an alteration study.

Luminescence in Exploration with Sam Cantor
For this episode we read a chapter from Sam Cantor's thesis entitled: Exploration Tool: Tracking Cryptic Alteration Surrounding the Iscaycruz Zn (Pb-Cu-Ag) Skarn-CRD Deposit, Central Peru (Cantor, 2020)
Have you implemented UV lamps into your exploration programs to help try and sort out complex mineralogy and vein paragenesis? Sam Cantor explains his side hustle at the Mineral Deposits Research Unit at the University of British Columbia, where he was able to start to build out workflows to tackle this in a complex skarn and carbonate replacement deposit in Peru.
If this has not yet peaked your interest, perhaps come for the tea where he talks about his role as a green junior geologist in Nicaragua using hyperspectral to overturn high sulfidation epithermal mineral identifications using the field geologist's tried and true method of tasting minerals :)

Dipping our toes into mesothermal gold with Jeff Bigelow
Honestly... I don't know which is more interesting... the content of the mesothermal gold chat or the tea.
Almost 17 years after the work was originally presented, we dive into Jeff's honors project - a study on gold mineralization at the Callie Deposit, Dead Bullock Soak, NT, Australia. The evolution of the research to present day is fascinating for all the fans who have asked for some orogenic gold love on the show!
