PGE, Cr & crystal mushes with Jason Coumans

For this episode we read: "Rapid crystallization of precious-metal-mineralized layers in mafic magmatic systems" (Hepworth et al., 2020). What does a computational geochemist and igneous petrologist do? Apparently, they think a lot on crystal mushes and bifurcation. Seeing mafic magmatic PGE and Cr systems from an igneous petrology perspective has its benefits and there's something in this episode for everyone interested in these systems. Separately, we also asked about his views on predatory scientific journals and their implications for geoscientists and researchers.
