In maxgav13/GMisc: Miscellaneous Functions for Geology (and its areas)

CIPW Norm

Description

CIPW() calculates the mineral composition of an igneous rock sample, based on ther major oxides and weight percent

Usage

CIPW(data)

Arguments

data	A dataframe (tibble) with the major oxides in the first column and their percent weight in the second column

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

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

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))
