Writeup from MB 88:
Northwest Africa 969 Morocco Purchased 2001 June/October Ordinary chondrite (LL6/7) A small stone was purchased from a Moroccan dealer by A. and G. Hupé (xHupé) in 2001 June, and subsequently seven more stones were purchased bringing the total weight to 463 g. Classification and mineralogy (A. Irving and S. Kuehner, UWS): Genomict breccia consisting of angular clasts in a finer grained matrix. Mostly olivine (Fa30.2-31.0, FeO/MnO = 57.7) exhibiting 120° grain junctions, with interstitial troilite and Fe-Ni metal (30% Ni), and accessory orthopyroxene (Fs24.9-25.0Wo1.5-2.3, CaO for 2 analyzed grains are 0.76 and 1.16 wt.%, FeO/MnO = 37.6), chromite, chlorapatite, interstitial sodic feldspar (Ab85Or5), and fine-grained intergrowth patches. Silicate minerals contain trains of fluid inclusions. Rare relict chondrules are present. Oxygen isotopes (D. Rumble, CIW): analyses of two whole rock fragments by laser fluorination gave δ18O = +5.3 ± 0.1‰, δ17O = +4.0 ± 0.1‰, Δ17O = +1.22 ± 0.03‰. Specimens: type specimen, 20 g, and three polished thin sections, UWS; main mass, xHupé. | ||||||||||||||||||||||
