| Summary: | Two locations on James Ross Island were sampled for basalts and olivines contained within them. During a detailed mineralogical and geochemical study it was shown that the olivines are non-altered and do not represent mantle-derived xenocrysts. Their trace element composition does not deviate significantly from other back-arc basins and the parent mantle-derived melt does not show signature of contamination by a subducted oceanic crust. |
