Geochemistry of basalt from the Polaris hydrothermal field, Gakkel Ridge

This dataset contains bulk geochemistry of pillow basalt collected at the Polaris hydrothermal field on the ultraslow-spreading Gakkel Ridge, Arctic Ocean. The samples were collected during R/V Polarstern Expedition PS101. Major elemental compositions were obtained via X-ray fluorescence spectrometry on fused glass beads. Details on the analytical procedure and uncertainties can be found in Albers et al. (submitted).
