Mineralogical comparison of the Y86032-type lunar meteorites to feldspathic fragmental breccia 67016
1990
Mineralogical characteristics of lunar meteorites Y82193 and Y86032 were compared to those of Apollo-16 fieldspathic fragmental breccia 67016, using results from electron microprobe analysis and TEM. It was found that the pyroxene mineralogy and chemistry of granulitic clasts in 67016 breccia and the Y86032-type lunar meteorites were much alike, suggesting that the formation processes of the fieldspathic fragmental breccias are also important in the genesis of lunar meteorites. There were differences in matrix microtextures, however, implying that 67016 and Y86032-type breccia formation temperatures were different.
