Provenance discriminant function diagram of Roser and Korsch (1988). The discriminant functions are: Discriminant Function 1 = (− 1.773•TiO2) + (0.607•Al2O3) + (0.760•Fe2O3) + (− 1.500•MgO) + (0.616•CaO) + (0.509•Na2O) + (− 1.224•K2O) + (− 9.090); Discriminant Function 2 = (0.445•TiO2) + (0.070•Al2O3) + (− 0.250•Fe2O3) + (− 1.142•MgO) + (0.438•CaO) + (1.475•Na2O) + (1.426•K2O)v+ (− 6.861)
