Writeup from MB 110:
Ramlat Fasad 548 19°09.463’N, 53°26.404’E Zufar, Oman Find: 2017 Feb 10 Classification: Carbonaceous chondrite (CO3) History: Eight fragments were found in close proximity during a search for meteorites. Physical characteristics: Reddish brown broken fragments, maximum size 4 × 4 cm, no fusion crust. Petrography: (Åke Rosén, E. Gnos, B. Hofmann) Chondrules, and CAIs and olivine grains (up to 1 mm) in dark-brown matrix. Typical size of chondrules 0.2-0.6 mm. Grains of FeS (to 50 μm) and iron metal (to 20 μm) are present in matrix and chondrules, but most of these minerals are altered. Unshocked (S1), strongly weathered, olivine is partially altered. Geochemistry: (Å. Rosén) Olivine Fa18.1±16.6, range Fa0.7-44.2 (N = 53). Orthopyroxene Fs7.1±13.4Wo2.2±1.9 (N = 4). Oxygen isotopes: (R. Greenwood, OU) δ18O = -0.502 δ17O = -4.907 Δ17O = -4.646 (all permil). Classification: Based on chondrule size, texture, mineralogy and oxygen isotopes this is a carbonaceous chondrite of type CO3. Strong weathering, unshocked (S1). Specimens: 22.28 g and one polished thin section at NMBE. Main mass: MHTO. | ||||||||||||||||||||||||||||||||||||||||
