Northwest Africa 11752 (NWA 11752)(Northwest Africa)Purchased: 2017Classification: Ordinary chondrite (LL3.05)Physical characteristics: Dark brown stone. Cut surface reveals packed well-defined chondrules in a brown matrix.Petrography: (J. Gattacceca, H. Pourkhorsandi, CEREGE; Lydie Bonal, IPAG) Large and closely packed chondrules. Opaques are FeNi minerals and troilite. Based on the structural order of the polyaromatic matter assessed by Raman spectroscopy, this meteorite appears to be as metamorphosed as ALHA 77307 (CO3.05). The Raman spectroscopy parameters of interest are FWHM-D (cm-1)=210.9±14.8, ID/IG=0.95±0.05 (see Bonal et al. 2016, GCA 189:312-337, figure 7).Geochemistry: Olivine Fa16.8±5.4, range Fa8.6-24.9, PMD 27% (N=6), Cr2O3 in ferroan olivine 0.45±0.05 wt% (N=6). Orthopyroxene Fs10.4±8.4Wo1.6±1.3 (N=4). Magnetic susceptibility log χ (× 10-9 m3/kg) = 4.00.Classification: LL3.05. Subtype from Raman spectroscopy and Cr2O3 content in ferroan olivine.Specimens: Type specimen at CEREGE. Main mass with Kuntz.Data from:
