Lunar Meteorite: Dhofar 2101

from The Meteoritical Bulletin, No. 104

Dhofar 2101 (Dho 2101)

Zufar, Oman
Found: 2016
Mass: 13 g (1 piece)

Classification: Lunar meteorite

History: The meteorite was found in 2016 during a field trip in the Oman desert.

Physical characteristics: Flattened brownish stone without fusion crust.

Petrography: (Ansgar Greshake, MNB) The meteorite is a feldspathic breccia composed of mineral fragments and basaltic clasts in a fine-grained groundmass. Most abundant minerals are calcic plagioclase and pigeonite; less abundant are augite and Fe-rich olivine. Accessories include FeS, ilmenite, and chromite. The meteorite contains calcite-filled veins due to terrestrial alteration.

Geochemistry: olivine: Fa_43.1±3.5 (Fa_34.9-45.7, FeO/MnO=105±12, n=20); pigeonite: Fs_32.9±2.4Wo_10.5±2.6 (Fs_28.7-36.5Wo_6.1-15.8, FeO/MnO=59±6, n=20); Ca-pyroxene: Fs_20.2±2.1Wo_35.0±3.9 (Fs_16.1-23.8Wo_27.9-41.0, FeO/MnO=54±8, n=11); calcic plagioclase: An_96.5±0.5 (An_95.4-97.0, n=13).

Classification: Lunar feldspathic breccia.

Randy Says…

I have not studied Dhofar 2101. It was found 10 km from paired stone Dhofar 1627/1980, so it may also be a stone of the pair group. The petrographic description does not suggest pairing, however.
