Whole Rock geochemical data for rock samples from this project
XRF geochemical major and trace element data of whole rocks from samples collected from Heard Island, Kerguelen Plateau. Samples that did not show alteration were used for the analysis. Whole rocks were crushed in an agate mill and analysed at the University of Tasmania XRF Facilities between 2014-2...
