Compositional boundary layers trigger liquid unmixing in a basaltic crystal mush
peer reviewed The separation of immiscible liquids has significant implications for magma evolution and the formation of magmatic ore deposits. We combine high-resolution imaging and electron probe microanalysis with the first use of atom probe tomography on tholeiitic basaltic glass from Hawaii, th...
