Writeup from MB 110:

Dhofar 2116 (Dho 2116)        19°25.472’N, 54°04.984’E

Zufar, Oman

Find: 19 Jan 2018

Classification: Ureilite

History: A single meteorite was found during a search for meteorites.

Physical characteristics: Fragment, one surface with regmaglypts and traces of fusion crust, 20x14x13 cm

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 1-3 mm. Olivine rims are reduced (width 150-200 μm) and contain abundant tiny metal blebs that are largely oxidized due to terrestrial weathering. Carbon platelets (up to 1 mm length) consist mainly of diamond and minor microcrystalline graphite. Silicates are weakly shocked (S2). Weathering moderate (most iron oxidized, silicates are unaffected).

Geochemistry: (J. Pape, NMBE) Olivine cores Fa21.0±1.4, Fe/Mn 42±4, Cr2O3 0.80±0.09 wt% (N = 19), reduced Ol rims have Fa>1.9. Pigeonite has Fs18.7±0.1Wo5.6±0.1, Cr2O3 1.09±0.03 wt% (N = 16).

Classification: Based on texture, mineralogy and geochemistry this is an unbrecciated, monomict, ferroan ureilite. Paired with Dhofar 2115

Specimens: All at NMBE, including one polished thin section.
