Olivine-melt relationships and syneruptive redox variations in the 1959 eruption of K$\bar{i}$lauea Volcano as revealed by XANES

The 1959 summit eruption of K$\bar{i}$lauea Volcano exhibited high lava fountains of gas-rich, primitive magma, containing olivine + chromian spinel in highly vesicular brown glass. Microprobe analysis of these samples shows that euhedral rims on olivine phenocrysts, in direct contact with glass, va...
