A note on the Apollo 15 green glass vitrophyresThe paper discusses the vitrophyric fraction of Apollo 15 green glasses which contain skeletal crystals of olivine. Although the crystals are uniform in composition, the coexisting glass shows a range in composition and an olivine subtraction trend. The data suggest that the vitrophyres are part of the traditional Apollo 15 green glass suite composition; the natural trend of rapid low pressure crystal-fractionation suggests that other VLT rock types cannot be derived from Apollo 15 green glass magma.
