a numerical matrix; the whole-rock data to be recalculated. |
Various petrochemical indexes are calculated, such as:
total iron as Fe2O3
Fe2O3/FeO, Na2O/K2O and K2O/Na2O ratios
Larsen's DI - Differentiation index (Larsen 1938)
Kuno's SI - Solidification index (Kuno 1959)
Agpaitic index (Ussing 1911)
