Khawr al Fazra 008 (KaF 008)        19°26.244’N, 50°48.638’E

Ash Sharqiyah, Saudi Arabia

Found: 15 Feb 2013

Classification: Carbonaceous chondrite (CO3)

History: Found by Edwin Gnos, Beda Hofmann, Ayman Majoub during search for meteorites on small patch of desert soil between dunes on February 15, 2013.

Physical characteristics: Dark brown, wind-polished fragment of 1.15 g.

Petrography: Chondrules (average size 0.21±0.13mm, n=79, maximum size 0.92 mm) constitute approx. 30 % in fine grained matrix (approx. 70%). Abundant iron sulfides (pyrrhotite and pentlandite) and magnetite. Metal droplets in chondrules and matrix. Matrix impregnated by iron hydroxides from terrestrial alteration.

Geochemistry: (N. Greber, Bern) Olivine compositions are Fa0.9-54.5, median Fa1.4 (n=23), clinopyroxene compositions are Fs0.6-38.6Wo0.8-3.2, median Fs13.7Wo1.6 (n=11) with some diopside Fs1.2-3.2.6Wo50.9-53.0 (n=3). Oxygen isotopes (R. Greenwood, OU): Sample cleaned with HCl yielded δ18O = -5.39, δ17O = -9.47, Δ17O = -6.66 (all per mil).

Classification: Based on mineral compositions, chondrule size and oxygen isotopes this is a CO3 carbonaceous chondrite.

Specimens: All material at MHNGE.
