In-situ Fe3+/∑Fe ratios and major, volatile, and trace element concentrations for Manus Basin back-arc pillow glasses and olivine-hosted melt inclusions

This dataset includes in-situ measurements of Fe3+/∑Fe ratios in pillow glasses and olivine-hosted melt inclusions from the Manus Basin back-arc, western Pacific. This dataset also includes in-situ measurements of major, volatile, and trace element concentrations in olivine-hosted melt inclusions and select pillow glasses from the Manus Basin back-arc. Data for melt inclusions are measured values, not corrected for post-entrapment crystallization.
