Dhofar 303

Oman
Found: 2001 June 28
Mass: 4.15 g (1 piece)

Lunar meteorite (anorthositic impact melt conglomerate)

A light grey stone weighting 4.15 g was found in the Dhofar region of Oman.

Mineralogy and classification (M. Nazarov, Vernad; L. Taylor, UTenn): fusion crust is absent; meteorite has a typical conglomerate texture; rounded lithic clasts are cemented by a very fine-grained impact melt matrix; clasts of impact melt breccias are most abundant and show commonly breccia-in-breccia textures; primary igneous rocks and granulites are rare and have mainly anorthositic and troctolitic compositions; feldspar, An_94-99; orthopyroxene, Wo_1-5En_19-89; clinopyroxene, Wo_6-46En_29-70; olivine, Fo_48-88 (Fe/Mn ~87 atom%); accessory minerals are Ti-rich chromite, ilmenite (3-6 wt% MgO), Al-Cr-Zr-rich armalcolite, rutile, troilite, and FeNi metal (1-37 wt% Ni; 0.2-2.3 wt% Co); composition of the impact melt matrix is SiO₂ = 44.0, TiO₂ = 0.15, Al₂O₃ = 29.8, Cr₂O₃ = 0.06, FeO = 3.17, MnO = 0.06, MgO = 4.91, CaO = 17.0, Na₂O = 0.34, K₂O = 0.01, P₂O₅ = 0.03 (wt%); the stone is moderately weathered; celestite, barite, gypsum, calcite and Fe hydroxides are present. The conglomerate texture and degree of weathering distinguish Dhofar 303 from Dhofar 302 and Dhofar 081/280, which were found nearby. However the meteorites may be paired.

Olivine: Fa₁₅ to Fa₂₄ with FeO/MnO (wt%) = 78. Fine Ca carbonate veins penetrate into the specimen. Unlike known lunar meteorites, this lunar rock is a feldspathic crystalline matrix breccia. The most Mg-rich pyroxene is more Mg-rich than those of common lunar regolith breccias and similar to those of 60019, an Apollo 16 breccia containing poikilitic clasts.

Dhofar 2047

Oman
Found: 2014 March 12
Mass: 4.95 g (1 piece)

Lunar meteorite (feldspathic breccia)

History: Found by a prospector.

Physical characteristics: Fusion crust is absent.

Petrography: Brecciated. Plagioclase is stained pink from hematite. No petrography in thin section was carried out because of the small stone mass.

Geochemistry: Bulk composition (R. Korotev, WUSL) INAA of subsamples gave the following mean abundances (in wt.%) FeO 3.1, Na₂O 0.35; (in ppm) Sc 4.6, La 0.8, Sm 0.33, Eu 0.74, Yb 0.26, Lu 0.040, Th 0.09.

Classification: Lunar (feldspathic breccia). The stone is indistinguishable in lithophile element composition from Dhofar 303, 305, 306, 309, 310, 908, 911, and 1085 and was found 0.7-1.6 km away from these.

Specimens: 1.14 g at UAb.

Randy Says…

The Dhofar 303 clan is unique among lunar meteorites in being highly feldspathic (~28% Al₂O₃), troctolitic (~Fo₇₈), and low in KREEP elements (0.3-0.4 ppm Sm).
