【NWA7034】 This is 1 of 18 approved meteorites classified as Martian (polymict breccia). History: Purchased by Jay Piatek from AHabibi in Morocco, 2011. Physical characteristics: Single stone, shiny, black surface, saw cut reveals porphyritic breccia with numerous dark and light colored phenocrysts and clasts of variable size and texture, set in a dark groundmass, many reflective opaques visible. Petrography: (C. Agee, UNM) Microprobe examination of two polished epoxy mounts show a porphyritic, brecciated texture with plagioclase and pyroxene phenocrysts to 5 mm, ubiquitous chlorapatite, ilmenite, magnetite, and trace K-feldspar. Fine-grained groundmass composed of plagioclase, pyroxene, oxides, and trace Fe-sulfides. Poikilitic pyroxene-plagioclase clasts and quench melt clasts present. No Fe-Ni metal observed. Geochemistry: (C. Agee , N. Wilson, F. McCubbin, UNM) Plagioclase Ab52±6An45±7Or3±1, n=10, low-Ca pyroxene Fs31.6±6.7Wo3.1±0.8, Fe/Mn=37±3, n=23, pigeonite Fs35.5±3.5Wo8.0±3.3, Fe/Mn=34±1, n=8, augite Fs24.3±4.5Wo38.7±4.6, Fe/Mn=32±6, n=12, apatite with Cl=4.85±0.34 F=0.70±0.13 F+Cl=-O 1.38±0.06 (wt%) n=16, ilmenite with up to 5.3 wt% MgO, magnetite with up to 22.5 wt% Cr2O3, K-feldspar Or77Ab21An3. Oxygen isotopes (Z. Sharp, UNM): acid-washed material analyzed in replicate by laser fluorination gave, respectively δ18O=6.00, 5.79, 6.51, 6.32; δ17O=3.76, 3.52, 4.09, 3.89; Δ17O= +0.59, +0.46, +0.65, +0.55 (all per mil). Classification: Achondrite ungrouped (basaltic breccia). Plagioclase and pyroxene compositions similar to basaltic shergottites, however the oxygen isotopic values are higher than the SNC fractionation array. Specimens: 30 g including a probe mount on deposit at UNM, Jay Piatek holds the main mass.
