This contribution is a dataset of in situ mineral major, minor and trace element concentrations in primary minerals of 18 olivine gabbros from Hole U1473A recovered at the Atlantis Bank Oceanic Core Complex (57°E, Southwest Indian Ridge). The samples were collected during the International Ocean Discovery Program Expedition 360, which aimed at understanding the architecture of ultraslow-spreading oceanic crust and investigating the processes involved in its formation. The minerals analyzed include olivine, plagioclase and clinopyroxene displaying variable grain-sizes from coarse-grained crystals to medium- and fine-grained crystals. The analyses were performed at Géosciences Montpellier - University of Montpellier (France) using electron microprobe, for major elements, and High Resolution - Inductively Coupled Plasma Mass Spectrometry, coupled with laser ablation system, for minor and trace elements. About 600 analyses are compiled here to investigate the magmatic processes, including magmatic crystallization and mineral-melt interactions during melt porous flow migration, that occur in lower crustal crystal mushes and that contribute to the building of the oceanic crust.
