Writeup from MB 95:

Dhofar 1443 18°25.00′N 54°25.50′E

Oman

Find: 12 April 2001

Lunar (anorthositic breccia)

History: On April 12, 2001, one stone was found by an anonymous finder in the Dhofar region, Oman. Some years later three further tiny fragments were found within a few feet. The total mass of all stones is 36.7 g.

Physical characteristics: The rock is slightly weathered and relatively dark in hand specimen.

Petrography and mineralogy (A. Bischoff, IfP and E. H. Haiderer, Vienna): typical anorthositic breccia with light anorthositic clasts and abundant impact melt clasts embedded within a tough, partially molten matrix. This mostly devitrified matrix contains abundant vesicles and schlieren. Based on the optical appearance the rock has some similarities with Dhofar 081, however, the coordinates do not favor pairing.

Mineral compositions: feldspar ranges from An_83–98with a mean of An_{94.8 ± 3.5}; pyroxene is Fs_12–49; mean: Fs_{30 ± 9}; and olivine is Fa_19–52; mean: Fa_{35.5 ± 9}.

Classification: Lunar (anorthositic breccia).

Type specimens: 7.4 g and one polished thin section (IfP, Mün); an anonymous collector holds the main mass.
