a Abbreviations: bdl = below detection limit; bG = bluish green, lt. = light, med. = medium, dk. = dark, Int. = intense, sl. = slightly, v.st. = very strongly.
b Oxides analyzed by electron microprobe; average of three analyses per sample on different spots (four analyses of sample N3). For complete electron
microprobe analyses, including the calculated ions per formula unit, see the G&G Data Depository.
c BeO was calculated based on an assumed stoichiometry of 3 Be atoms per formula unit.
d Trace elements analyzed by LA-ICP-MS; average of three analyses per sample on different spots (two analyses of sample N7).
