Abbreviation: NWA 8738 Observed fall: No Year found: 2009 Country: (Northwest Africa) Mass 2.85 kg Classification history:Meteoritical Bulletin: (2016) LL3-6Recommended: LL3-6 This is 1 of 31 approved meteorites classified as LL3-6. Comments:Approved 31 Mar 2016 Northwest Africa 8738 (NWA 8738)(Northwest Africa)Purchased: 2009Classification: Ordinary chondrite (LL3-6)History: Purchased by Blaine Reed in Tucson, 2009.Physical characteristics: Four fragments. Saw cuts show brecciated texture, dark and light clasts set in a light-gray groundmass, scattered metal/sulfide grains.Petrography: (C. Agee) Microprobe examination of a polished mount reveals a polymict breccia with at least three distinct lithologies corresponding to LL3, LL6, and L6. Type 6 is ~75%, type 3 is ~25%. The type 3 lithology has some PO chondrules with igneous zoning, also PP chondrules with enstatitic pyroxenes, BO chondrules, all with mesostasis or glass, whereas the type 6 lithologies have a few relict chondrules, and appear to be mostly recrystallized, with equilibrated olivines and pyroxenes, and plagioclase >100 μm. Ubiquitous troilite, kamacite, chromite, and Cl-rich apatite.Geochemistry: (C. Agee, UNM) L6 component: olivine 25.5±0.2, Fe/Mn=50±3, n=4; low-Ca pyroxene Fs22.7±0.4Wo1.2±0.4, Fe/Mn=33±1, n=4. LL6 component: olivine 29.4±0.9, Fe/Mn=60±3, n=17; low-Ca pyroxene Fs25.2±0.0Wo1.2±0.1, Fe/Mn=38±0, n=3. LL3 component: porphyritic pyroxene chondrule Fs4.4±0.4Wo0.2±0.1, Fe/Mn=12±1, n=4. Random olivines range Fa16.5-29.9, Fa25.8±5.2, Fe/Mn=55±9, n=10.Classification: Ordinary chondrite (LL3-6), breccia of LL3, LL6, and L6 components, weathering grade W1, shock stage S4.Specimens: 23.6 g including a probe mount on deposit at UNM, Reed holds the main mass.I will combine the cost of shipping for all the items you win during a 2 week period that are paid for in a single transaction.
