Ramlat Fasad 544        19°06.396’N, 53°20.176’E

Zufar, Oman

Find: 2017 Feb 05

Classification: Carbonaceous chondrite (CO3)

History: Found during a search for meteorites.

Physical characteristics: Single dark reddish brown fragment, no fusion crust preserved.

Petrography: (Åke Rosén, E. Gnos, B. Hofmann) Chondrules, and CAIs and olivine grains (up to 0.8 mm) in dark-brown matrix. Typical size of chondrules 0.2-0.3 mm. Partially altered troilite grains up to 100 μm are common, metal grains only rarely preserved. Unshocked (S1), strongly weathered.

Geochemistry: (Å. Rosén) Olivine Fa7.6±9.2, range Fa0.7-40.7 (N = 43). Orthopyroxene Fs1.6±1.4Wo1.8±2.3 (N = 9). Oxygen isotopes: (R. Greenwood, OU) δ18O = -0.246 δ17O = -4.677 Δ17O = -4.549 (all permil).

Classification: Based on chondrule size, texture and mineralogy this is a carbonaceous chondrite, type CO3, medium weathering, low shock.

Specimens: 1.7 g and one polished thin section at NMBE. Main mass: MHTO.
