Astromat

This dataset presents secondary ion mass spectrometry measurements of total H, presented as H2O equivalents, in nominally anhydrous minerals from tafassite and brachinite group meteorites. In general, reported concentrations are presented as grain averages for each meteorite and have undergone corrections for analytical drift and the analytical background. The purpose of this dataset is to provide a first-order constraint on the H budgets of tafassite and brachinite group meteorites and their parent bodies.
