Chemical Composition of Volcanic Rocks from Kilauea Iki
Description
This dataset contains the chemical composition of volcanic rocks sampled from the lava lake at Kilauea Iki (Hawaii). The data represents major oxide concentrations in fractional form.
Usage
kilauea_iki
Format
A data frame with 17 observations and 11 variables:
- SiO2
Silicon dioxide (fraction)
- TiO2
Titanium dioxide (fraction)
- Al2O3
Aluminium oxide (fraction)
- Fe2O3
Ferric oxide (fraction)
- FeO
Ferrous oxide (fraction)
- MnO
Manganese oxide (fraction)
- MgO
Magnesium oxide (fraction)
- CaO
Calcium oxide (fraction)
- Na2O
Sodium oxide (fraction)
- K2O
Potassium oxide (fraction)
- P2O5
Phosphorus pentoxide (fraction)
Details
The variability in the oxide concentrations is attributed to magnesic olivine fractionation, starting from a single magmatic mass as suggested by Richter & Moore (1966).
