Writeup from MB 103:

Khawr al Fazra 006 (KaF 006)        19°38.041’N, 50°40.066’E

Ash Sharqiyah, Saudi Arabia

Found: 15 Feb 2013

Classification: Carbonaceous chondrite (CK6)

History: Found by Saud Nasir Al Tamimi during search for meteorites on small patch of desert soil between dunes on Feb. 15, 2013.

Physical characteristics: Dark greenish grey individual of 59.0 g, with minor remaining fusion crust. Cemented dune sand attached.

Petrography: Chondrules (average size 0.87±0.32 mm, n=30, maximum size 1.7 mm) are abundant but poorly delineated in a strongly recrystallized matrix with an average grain size of 50 μm. Feldspar is typically >50 μm in size. Abundant magnetite, sulfides largely weathered. Shock grade S2.

Geochemistry: (N. Greber, Bern) chondrule olivine compositions are Fa25.8-28.3, median Fa26.4 (n=28), pyroxene compositions are Fs20.4-25.4Wo0.6-6.9, median Fs23.3Wo1.0 (n=5). Matrix olivine has a composition of Fa26.4±0.6 (n=14). Oxygen isotopes: (R. Greenwood, OU) gave δ18O=0.98, δ17O=-3.46, Δ17O= -3.97 (all per mil).

Classification: Based on chondrule size, homogeneous silicate composition and matrix plagioclase size, the meteorite is classified as a CK6 carbonaceous chondrite.

Specimens: 12.1 g and one polished thin section at MHNGE. Remaining material at SGS.
