The `kilauea_iki` data set contains the chemical composition of volcanic rocks sampled from the lava lake at Kilauea Iki (Hawaii). The data represent major oxide concentrations in fractional form.
kilauea_ikiA data frame with 17 observations and 11 variables:
Silicon dioxide
Titanium dioxide
Aluminium oxide
Ferric oxide
Ferrous oxide
Manganese oxide
Magnesium oxide
Calcium oxide
Sodium oxide
Potassium oxide
Phosphorus pentoxide

The variability in oxide concentrations is attributed to magnesian olivine fractionation from a single magmatic mass, as suggested by Richter and Moore (1966).
