Dilek et al. Pearce, 1983 Th - Ta - Yb discriminant for mantle melting array vs. The diagrams below are those I have used, or tried to use, at one time or another. Cr discriminant for ocean floor basalts vs.
It is a senseless waste of time for everyone else to have to do the same thing, so I present the coordinates for the benefit of all humanity. All discriminant line coordinates are given in Excel files with X and Y values, Z if necessary.
