Lunar meteorite (feldspathic breccia)
History: Purchased by by Darryl Pitt and David Gheesling from a dealer in Zagora, Morocco, in 2012 February.
Bulk composition: (R. Korotev, WUSL): mean values from INAA of subsamples are 6.2 wt.% FeO, 11.8 ppm Sc, 310 ppm Ni, 10.5 ppm La, 4.8 ppm Sm, 0.94 ppm Eu, 3.5 ppm Yb, 1.9 ppm Th.
NWA 7274 is a feldspathic lunar meteorite moderately rich in KREEP. Like the 4936 clan, it bears some compositional resemblance to Apollo 16 soils, but it’s compositionally distinct from NWA 4936 and not as glassy.
