Writeup from MB 111:
Northwest Africa 14448 (NWA 14448) (Northwest Africa) Purchased: 2021 Jun Classification: HED achondrite (Howardite) History: Purchased by Craig Zlimen and Brett Cohen in June 2021 from an Algerian dealer. Petrography: (A. Irving, UWS and P. Carpenter, WUSL) Complex polymict breccia containing a variety of lithic clasts with both diogenitic and eucritic mineral compositions, plus related mineral debris of (ranging widely in grainsize). Estimated proportions are ~60 vol.% diogenitic material and ~40 vol.% eucritic material; minor dark, fine grained carbonaceous chondrite clasts are also present. Accessory phases include silica polymorph, fayalite, ilmenite, low-Ti chromite and minor secondary calcite; no metal was observed. Geochemistry: Diogenitic orthopyroxene (Fs19.2-26.0Wo1.4-4.1, FeO/MnO = 25-29, N = 3), eucritic low-Ca pyroxene hosts (Fs45.3-52.3Wo1.6-3.7, FeO/MnO = 29-30, N = 3), eucritic augite exsolution lamellae (Fs17.7-24.4Wo44.3-38.5, FeO/MnO = 25-28, N = 3), low-Ca pyroxene (Fs42.4Wo2.0, FeO/MnO = 31), pigeonite (Fs54.1Wo13.6, FeO/MnO = 31), augite (Fs31.7-33.7Wo43.6-37.9, FeO/MnO = 32-33, N = 2), diogenitic olivine (Fa 31.9-32.2, FeO/MnO = 39-42, N = 2), fayalite (Fa86.6, FeO/MnO = 39), plagioclase (An88.5-91.9Wo0.4-0.2, N = 4). Carbonaceous chondrite clast: olivine (Fa29.3±16.4, range Fa0.5-47.1, N = 7), low-Ca pyroxene (Fs2.5Wo3.8), subcalcic augite (Fs3.7Wo31.4). Classification: Howardite. Specimens: 24.6 g including one polished thin section at UWB; remainder with Mr. C. Zlimen and Mr. B. Cohen. | ||||||||||||||||||||||||||||||
