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.
type specimen, 0.8 g plus a thin section, Vernad; main mass with
Dhofar 302 is not paired with Dhofar 081/280. See this.
