Writeup from MB 103:
Khawr al Fazra 005 (KaF 005) 19°17.461’N, 50°09.565’E Ash Sharqiyah, Saudi Arabia Found: 13 Feb 2013 Classification: Carbonaceous chondrite (CV3) History: Found by Edwin Gnos, Beda Hofmann and Ayman Majoub during search for meteorites on small patch of desert soil between dunes on February 13, 2013. Physical characteristics: 20 fragments, maximum size 3.5 cm, combined mass 47.68 g. No fusion crust. Petrography: (E. Gnos, MHNGE and B. Hofmann, NMBE) The meteorite consists of up to 2.0 mm sized, glass-containing chondrules (average size 0.95±0.35 mm n=42, maximum size 1.65 mm) constituting approx. 35 vol%, fine-grained convoluted CAIs (0.25- 6.0 mm; approx. 5 vol%), and dark matrix (approx. 60 vol%). Magnetite is abundant, troilite very rare. All fragments are partially covered by soil-derived gypsum. Geochemistry: (N. Greber, Bern) Olivine compositions are Fa0.3-59.5, median Fa32.5 (n=10), pyroxene compositions are Fs0.6-0.9Wo1.0-44.3, median Fs0.7Wo4.0 (n=11). Oxygen isotopes: (R. Greenwood, OU) gave δ18O = 1.77, δ17O = -2.89, Δ17O = -3.81 (all permil). Classification: CV3 based on petrography, matrix abundance, mean chondrule size, presence of large CAIs and oxygen isotopes. Specimens: 15.78 g and one polished thin section at MHNGE. Remaining material at SGS. | ||||||||||||||||||||||||||||||||||||||
