Mass: 3.83 g
meteorite (anorthositic impact melt breccia)
dark grey stone weighing 3.83 g was found in the Dhofar region of Oman.
and classification (M. Nazarov, Vernad; L. Taylor, UTenn):
fusion crust is absent; meteorite is a clast-rich impact melt breccia; mineral
fragments and lithic clasts are set within a poorly crystallized impact
melt glassy matrix; impact melt breccias are most abundant in the lithic
clast population; fragments of primary igneous rocks and granulites of
anorthositic, gabbro-noritic, and troctolitic compositions are common; rare
glass fragments of KREEP composition were found; mare basalt material is
probably present; feldspar, An90-99; orthopyroxene, Wo1-4En45-88;
clinopyroxene, Wo6-46En2-83, olivine, Fo8-94
(Fe/Mn ~86 atom%); accessory minerals are Ti-rich chromite, Mg-Al-spinel,
ilmenite (0.4-6 wt% MgO), baddeleyite, silica, tranquilityite (?),
troilite, and FeNi metal (0.7-44 wt% Ni; 0.2-1.4 wt% Co); composition of
the impact-melt glassy matrix is SiO2 = 44.5, TiO2 =
0.27, Al2O3 = 28.1, Cr2O3 =
0.09, FeO = 4.02, MnO = 0.06, MgO = 4.84, CaO = 16.5, Na2O =
0.41, K2O = 0.09, P2O5 = 0.12 (wt%);
terrestrial weathering is not significant. Dhofar 302 and Dhofar 081/280
were found nearby and are possibly paired. However, Dhofar 302 seems to be
poorer in glass and richer in igneous and granulitic lithologies.

Dhofar 302 is not paired with Dhofar 081/280. See this.
