Dhofar 2115 (Dho 2115)        19°25.510’N, 54°05.038’E

Zufar, Oman

Find: 19 Jan 2018

Classification: Ureilite

History: A large meteorite broken into several large and >100 small pieces was found during a search for meteorites. Largest sample of a strewnfield consisting of 8 masses.

Physical characteristics: Large individual broken into many pieces, ablated surface with regmaglypts and traces of fusion crust present

Petrography: (J. Pape, E. Gnos, B. Hofmann) The sample consist mainly of olivine with minor pigeonite both with slight preferred grain orientation and shows the characteristic ureilitic texture. Typical grain size is 1.0-2.5 mm. Olivine rims are reduced (width 150-300 μm) and contain abundant tiny metal blebs that are largely oxidized due to terrestrial weathering. Carbon platelets (up to 1.5 mm length) consist mainly of diamond and some minor microcrystalline graphite. Silicates are weakly shocked (S2). Weathering moderate (most iron oxidized, silicates are unaffected).

Geochemistry: (J. Pape, NMBE) Olivine and pigeonite cores are homogeneous. Fa21.2±0.4, Fe/Mn 45±2, Cr2O3 0.74±0.02 wt% (N = 11), reduced Ol rims have Fa>2.0. Pigeonite has Fs18.3±0.3Wo5.5±0.1, Cr2O3 1.08±0.03 wt% (N = 18).

Classification: Based on texture, mineralogy and geochemistry this is an unbrecciated, monomict, ferroan ureilite.

Specimens: 134 g including one polished thin section at NMBE, main mass: MHTO
