Writeup from MB 103:

Khawr al Fazra 011 (KaF 011)        19°26.246’N, 50°48.647’E

Ash Sharqiyah, Saudi Arabia

Found: 15 Feb 2013

Classification: Enstatite chondrite (E5)

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

Physical characteristics: Dark brown fragment of 0.59 g, partially sand-encrusted.

Petrography: Chondrules and chondrule fragments (average size 0.37±0.17 mm, n=12, maximum size 0.83 mm) are set in matrix of enstatite and abundant iron (hydr)oxides (alteration products). Enstatite is often idiomorphic towards (former) metal and troilite. Feldspar is typically 10-20 μm in size. No olivine present. Rare graphite. Metal and sulfides are largely weathered, rare metal grains and some troilite are preserved (W3). Shock grade S2.

Geochemistry: (N. Greber, Bern) pyroxene compositions are Fs1.0-5.7Wo0.1-0.6, median Fs1.9Wo0.3 (n=14).

Classification: Based on the absence of olivine, pyroxene compositions and the presence of graphite this is an enstatite chondrite.

Specimens: All material at MHNGE.
