Classification: HED Ureilite, augite-bearing
Place/Time: 20 April 2014in Al Wusta, Oman
Mass: 30g

History: The meteorite was found on 20 April 2014 during a field trip in the Oman desert.

Physical characteristics: Brownish individual lacking any fusion crust.

Petrography: The meteorite is dominantly composed of <1 mm sized olivine grains, sometimes poikilitically enclosing augite crystals. Olivine shows abundant reduced rims; the meteorite contains flaky graphite and Cr-bearing sulfides. Cracks are often found to be filled with barite likely due to intense terrestrial weathering.

Geochemistry: Reduced rims in olivine: Fa1.4-4.5; olivine contains 0.28±0.03 wt% Cr2O3 and 0.22±0.02 wt% CaO; augite contains 1.58±0.03 wt% Cr2O3 and 3.37±0.03 wt% Al2O3

I keep this specimen for around four years on my window thinking it is just funny rock from my Oman trip. I was thinking to throw it away few times. Around 2 years ago I cut off small endpiece to look inside it, but I didnt find anything interesting (read meteorite related). Finally in 2018 I send that endpiece to A. Greshake to be 100% sure that its not meteorite before I throw it through my window. Confirmation that it is meteorite was most surprising information that I received.
