Writeup from MB 104:

Ramlat Fasad 027 18°46.804’N, 53°09.346’E

Zufar, Oman

Find: 10 Feb 2014

Classification: Carbonaceous chondrite (CO3)

History: Found by Edwin Gnos, Beda Hofmann, Thomas Burri, and Marianna Mészáros during a search for meteorites on February 10, 2014.

Physical characteristics: Two dark brown wind ablated fragments (7.04 and 3.81 g), found close to each other, no fusion crust preserved. Total mass is 10.85 g.

Petrography: (B. Hofmann, NMBE and E. Gnos, MHNGE) Homogeneous chondritic texture. Glass-bearing chondrules. CAIs are common. Mean apparent chondrule size is 0.30±0.11 mm (n=93). Matrix abundance ~30%. Contains iron metal and troilite, both are partly altered to (hydr)oxides.

Geochemistry: (N. Greber, Bern) Olivine compositions are Fa_29.7±10.9(Fa_0.6-36.9, n=26). Orthopyroxene compositions are Fs_5.7±1.5Wo_2.2±1.3(Fs_4.3-8.8Wo_0.4-4.2, n=11). Oxygen isotopes: (R. Greenwood, OU): δ¹⁸O=2.28, δ¹⁷O=-2.32, Δ¹⁷O=-3.51.

Classification: Based on petrography (including matrix abundance and chondrule size), geochemistry and oxygen isotopes this meteorite is a CO3 carbonaceous chondrite, unshocked (S1), medium weathering.

Specimens: All at NMBE
