Achondrite (eucrite)
History: A 330 g brecciated stone was purchased at the Tucson show by D. Gregory from an anonymous Moroccan dealer.
Petrology: (P. Warren, UCLA) An extremely fine-grained (0.01–0.1 mm) stone with thoroughly exsolved pyroxenes, some pyroxenes (<1 vol%) up to 0.6 mm in maximum dimension. Microphenocrysts are compositionally identical to the groundmass pyroxenes.
Geochemistry: Low-Ca pyroxene (En32.0Wo2.3); high-Ca pyroxene (En27.8Wo44.1). Bulk chemistry: (INAA, UCLA two chips) Al2O3 = 12.5 wt%, Na = 2.83 and 2.84 (both wt%); Sc = 32 and 33; Sm = 2.1 and 2.2 (both µg/g); Fe/Mn = 36, 37.
Classification: Achondrite (eucrite); low to moderate shock.
Specimens: A 20 g type specimen is on deposit at UCLA. Gregory holds the main mass.
