CIPW() calculates the mineral composition of an igneous rock sample, based on ther major oxides and weight percent
Value
Summary table for the CIPW norm, with all the minerals and their percent weight, as well as separate tables for the ferromagentic minerals and its components
Details
The names of the oxides must be: SiO2, TiO2, Al2O3, Fe2O3, FeO, MnO, MgO, CaO, Na2O, K2O, P2O5. If any of the major oxides is not present just use 0 for their percent weight
Examples
d = data.frame(O = c('SiO2', 'TiO2', 'Al2O3', 'Fe2O3', 'FeO',
'MnO', 'MgO', 'CaO', 'Na2O', 'K2O', 'P2O5'),
W = c(35.6,5.98,12.9,7.68,9.28,.05,
5.4,8.46,8.35,2.78,2.13))
