Petrology of Apollo 14 regolith breccias and ion microprobe studies of glass beadsMineral chemistries, glass chemistries, and bulk compositions of Apollo 14 regolith beccias are used to study the regolith evolution at the Apollo 14 site and on the moon in general. Major changes in the regolith since the formation of the breccias include an increase in maturity, an increase in glasses with the Fra Mauro basalt composition, and decreases in feldspathic and mare glasses. The results suggest the presence of a source with a larger non-KREEPy highland plutonic component than other breccias.
