Writeup from MB 110:

Ramlat Fasad 547        19°06.504’N, 53°29.523’E

Zufar, Oman

Find: 2017 Feb 10

Classification: Carbonaceous chondrite (CV3)

History: Found during a search for meteorites.

Physical characteristics: Single stone of dark olive-green color, 7 × 4 × 4 cm, strongly wind-ablated, with protruding chondrules. In a cut section, a fine-grained clast of 2 × 1 cm without chondrules is visible.

Petrography: (Åke Rosén, E. Gnos, B. Hofmann) Chondrules (0.6-2.0 mm), CAIs (up to 2 mm) and olivine grains (up to 1.5 mm) in fine-grained brown matrix constituting about 40 vol%. Magnetite, FeS and rare metal are only present in some chondrules. One chondrules contains xenomorphic chromite up to 80 μm in size. Low shock level (S2), medium weathering.

Geochemistry: (Å. Rosén) Olivine Fa11.3±8.4, range Fa0.3-35.5 (N = 54). Orthopyroxene Fs0.9±0.3Wo1.5±1.0 (N = 9). Oxygen isotopes: (R. Greenwood, OU) δ18O = 0.554 δ17O = -3.580 Δ17O = -3.868 (all permil).

Classification: Based on chondrule size, texture, mineralogy and oxygen isotopes this is a CV3 carbonaceous chondrite. However, it is essentially free of metal and magnetite, resulting in a low magnetic susceptibility and olive-green colour. Medium weathering, unshocked.

Specimens: 24.6 g and one polished thin section at NMBE. Main mass: MHTO.
