Petrography and Origin of the Unique Achondrite GRA 06128 & 06129: Preliminary ResultsGRA 06128 and 06129 are paired achondrites with unique mineral proportions (75% oligoclase), mineral compositions, and oxygen isotope ratios. They appear to represent alkalic igneous rock from a hitherto unsampled differentiated parent body, modified significantly by thermal and shock metamorphism.
