Details

Triangular diagram of Laurent et al. (2014, Fig. 6) with apices: Al2O3/(FeOt+MgO), 3CaO and 5K2O/Na2O (all in wt. %), serves to distinguish prospective sources of granitoids. It is based on compilation of a large database of experimental data - see Laurent et al. (2014 and references therein) for the citations of the original works.
