Extended Data Fig. 1: MgO/Al2O3 versus CaO/Al2O3 for the studied CE5 impact glass beads.
From: A solar wind-derived water reservoir on the Moon hosted by impact glass beads
Most smooth and homogeneous CE5 glass beads plot in the mare domain (Supplementary Table 2). Literature data for lunar impact and pyroclastic glasses in Apollo samples, Luna samples, and lunar meteorites (LMs) are from MoonDB (http://search.moondb.org) and are shown for comparison. Compositions of the CE5 bulk basalts and bulk soils (shaded yellow square) are from Tian et al.81 and Li et al.38. Classification of lunar glasses (dashed lines) is from Refs. 79,80.
