Writeup from MB 103:

Al Hawaya 002        19°50.603’N, 49°11.197’E

Ash Sharqiyah, Saudi Arabia

Found: 15 Feb 2013

Classification: Ureilite

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, wind-polished broken individual of 7.61 g. Strongly weathered.

Petrography: Polished thin section shows typical ureilitic texture with interlocked olivine and pyroxene grains typically 1 mm in size, with undulose extinction. Carbon platelets are very common (~10 vol%) and consist mainly of diamond. Metal and troilite are largely oxidized, only few remnant inclusions in silicates. Silicates are partly affected by terrestrial alteration.

Geochemistry: (N. Greber, Bern) Olivine compositions are Fa10.2-21.8, median Fa21.4, median Cr2O3 0.49 wt% (n=29), pyroxene compositions are Fs7.2-18.3Wo4.7-22.1, median Fs14.4Wo10.7, median Cr2O3 1.25 wt% (n=8). Bulk analysis of cut surface by XRF (wt%): Fe 17.0, Mn 0.28 (Fe/Mn 60.4), Ni 0.16, Cr 0.53.

Classification: Based on texture, silicate compositions and abundant diamond platelets this is a ureilite.

Specimens: 2.28 g and one polished thin section at MHNGE. Remaining material SGS.
