Chemical composition of volcanic rocks from Kilauea Iki

Description

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.

Usage

kilauea_iki

Format

A data frame with 17 observations and 11 variables:

SiO2

Silicon dioxide

TiO2

Titanium dioxide

Al2O3

Aluminium oxide

Fe2O3

Ferric oxide

FeO

Ferrous oxide

MnO

Manganese oxide

MgO

Magnesium oxide

CaO

Calcium oxide

Na2O

Sodium oxide

K2O

Potassium oxide

P2O5

Phosphorus pentoxide

Details

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