Replication data for: Silicon-oxygen isotope disequilibrium in the Kaapvaal craton mantle lithosphere: evidence for post-Archean silica-addition

Replication data for submitted manuscript "Silicon-oxygen isotope disequilibrium in the Kaapvaal craton mantle lithosphere: evidence for post-Archean silica-addition". Data includes stable Si and O isotope data for olivine, orthopyroxene and garnet minerals from Kimberley harzburgite xenoliths from the Kaapvaal Craton, South Africa. Data also includes supporting major and trace element geochemical mineral data as well as pressure-temperature calculations. Further information regarding methodology, calculations and visualisations can be found at linked manuscript (once accepted for publication).
