Writeup from MB 109:
Northwest Africa 13372 (NWA 13372) Morocco Purchased: 2019 Classification: Ordinary chondrite (H3-6) History: Purchased by S.Crivello and I.Pardini at the 2019 Genoa Mineral Show from a Moroccan dealer. Reportedly from the Dakhla region. Physical characteristics: Consists of four irregularly shaped masses, 2.45 kg, 3.15 kg, 1.136 kg and 518 g, found within meters of each other. All four masses are coated in red-brown desert varnish, at least in part. The largest mass also has light tan caliche and weathered fusion crust. Petrography: (C. Herd, UAb) Optical and microprobe examination of a polished thin section shows well-defined chondrules with some brecciation. A single 5 mm equilibrated (type 6) clast was observed in the thin section. Iron oxide veins and iron oxide staining are present throughout. Shock effects include undulatory extinction with >2° angular variation. Geochemistry: (C. Herd, UAb) Data obtained by EMP examination of carbon-coated thin section: Olivine Fa20.3±2.3 (n=87); Low-Ca Pyroxene Fs15.1±4.5Wo1.0±0.5 (n=61). Classification: Ordinary chondrite, H3-6. Equilibrated clasts within a type 3 matrix. Matrix subtype between 3.7 and 3.9 based on standard deviation of olivine and low-Ca pyroxene analyses. Specimens: Type specimen of 46.1 g, including one thin section, is at UAb. Main masses with S. Crivello and I. Pardini. | ||||||||||||||||||||||||||||||
