Abstract The gabbros of the Tertiary Kap Edvard Holm Layered Serieshave a stratigraphic thickness of more than 5000 m. Earlier work has shown that the range in cumulus mineral compositions is restricted (plagioclase An 81 —An 51 olivine Fo 85 —Fo 66 pyroxenes Ca 43 Mg 46 Fe 11 to Ca 43 Mg 37 Fe 20 )...
