  • The Sci-Fi and Facts of Orogenic Gold with Rich Goldfarb
    2024/12/11

    In this episode of GeOCHemISTea we dive into the origins of orogenic gold deposits with Rich Goldfarb, exploring the science behind fluids, isotopes, and formation processes. From debunking magmatic theories to highlighting the facts of metamorphic origins, Rich shares the real tea (and quite a number of shenanigans) on how to make an orogenic gold deposit . Join us for a conversation that’s equal parts science and intrigue.


    For this episode we read: Orogenic gold: is a genetic association with magmatism realistic? (Goldfarb and Pitcairn, 2022)

  • Exploring with pXRF and LIBS with Steve Tambanis
    2024/11/13

    In this episode of GeOCHemISTea, host Sam Scher sits down with Steve Tambanis, Managing Director at STX Consulting and Director at RealTime Priority Limited, to explore the challenges and innovations in field-based geochemical analysis using portable XRF (pXRF) and laser-induced breakdown spectroscopy (LIBS). Steve shares his journey from traditional exploration geology to pioneering real-time assays, recounting how he and his team set out to develop a portable field laboratory for immediate sample analysis in remote settings. Together, they dive into the highs and lows of calibrating and optimizing pXRF and LIBS, discussing the meticulous sample preparation and calibration required to achieve accuracy and reliability, even in challenging field conditions.

    From overcoming unexpected hurdles, like creating custom calibration pellets to ensure consistent LIBS results, to exploring the practical limits and advantages of each technology, this episode sheds light on the adaptability required to make these devices work effectively in geochemical exploration. Sam and Steve also touch on the importance of engaging with vendors for technical support and the value of sharing field-tested insights with other users to advance best practices. Whether you're an experienced geochemist or new to the field, Steve's experiences offer invaluable guidance for anyone interested in applying portable assay technologies to improve exploration outcomes.

  • Upscaling pyrite chemistry with 4-acid data with Aidan Kitchener
    2024/10/09

    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.

    For this episode we read: Using whole rock and in situ pyrite chemistry to evaluate authigenic and hydrothermal controls on trace element variability in a Zn mineralized Proterozoic subbasin (Magnall et al., 2022)
