NWA 11551 Howardite Meteorites for Sale
Location: Northwest Africa, exact location unknown.
Found: 2014
Classification: HED achondrite (Howardite)
Description: Physical characteristics: Exterior surfaces partly covered by black fusion crust; non-crusted surfaces show obvious breccia texture with variegated clasts up 1o 1 cm across. Most surfaces appear relatively unweathered but rust spots are present. Petrography: In thin section appears to be a roughly 50-50 mixture of diogenitic (coarse orthopyroxene) and eucritic (plagioclase, pyroxene-dominated) clasts. Some eucritic pyroxene shows zoning. Geochemistry: Diogenitic orthopyroxene Fs27.1±3.8Wo2.4±1.0 (N=182), eucritic low-Ca pyroxene Fs41.6±6.0Wo3.1±1.0 (N=40), augite Fs26.8±7.8Wo41.5±2.5 (N=30), uninverted pigeonite Fs48.8±5.8Wo8.0±2.3 (N=36), bulk inverted pigeonite Fs50.5±5.4Wo10.7±3.0 (N=24).
