Writeup from MB 110:
Northwest Africa 14252 (NWA 14252) (Northwest Africa) Purchased: 2019 Sep Classification: HED achondrite (Eucrite) Physical characteristics: Single stone, lacking fusion crust Petrography: (J. Gattacceca, CEREGE) Igneous rock with microgabbroic texture (grain size 150 µm). Main minerals are Ca-pyroxene and plagioclase. Pyroxene show both fine exsolution lamellae and zoning with Fe poor cores, sometimes in the same grain. Accessory minerals: ilmenite, chromite, primary baryte (with both euhedral and rounded shapes) set in plagioclase. Geochemistry: Pyroxene Fs41.6±4.8Wo29.4±5.9, range Fs36.8-48.0, FeO/MnO 32.8±1.9 (n=5), core Fs36.0Wo6.4 (n=1). Plagioclase An92.8±0.9Ab7.1±0.8Or0.1±0.1 (n=3). Classification: Achondrite (eucrite). The dominance of Ca-pyroxene over low-Ca pyroxene, the iron poor pyroxene cores and the abundance of euhedral baryte in plagioclase are unusual features. Specimens: Type specimen at CEREGE.
