For this episode we read: "A User's Guide to Basalt Discrimination Diagrams" by Pearce (1996).

Surely you have seen a geochemical diagram before... Winchester and Floyd (1977) for the classification of volcanic rocks or even Pearce's 1996 diagram to classify basalts. Have you combed the literature to find the most fit-for-purpose diagram for your own rock samples? Look no further! In this discussion with Pim van Geffen we talk about how to use the principles outlined in this book chapter to create your own diagrams.
