Sulfate recycling at subduction zones and sulfur isotopes with Libby Sharman

There 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.

As usual, my favorite part of the episode is Tea Time, but for a different reason. As an undergraduate, Libby asked a question to established researchers that were giving a talk to her university 8000+ of miles from their lab en route to do some fieldwork at the Platreef (Bushveld Complex, South Africa) that became a huge contribution to science and ore deposits research, as well as the focus for her MSc and PhD research. So cool.

For this episode we read:
Sulfate recycling at subduction zones indicated by sulfur isotope systematics of Mesozoic ultramafic island arc cumulates in the North American Cordillera (Milidragovic et al., 2023)
