The millications are used for many plots of the French school, e.g.
De la Roche et al. (1980) or Debon & Le Fort (1983, 1988).
The calculated values are Si, Ti, Al, Fe3, Fe2, Fe, Mn, Mg, Ca, Na, K, P

Element[i] = 1000 (Oxide[i] (wt. %)) / (MW(Oxide[i]) * (x(Element[i]) )
Where: MW = molecularWeight of the Oxide[i], x = number of atoms of Element[i] in its formula
