Lunar meteorite (anorthositic breccia)
A 1.425 kg stone was found in Dar al Gani in the Libyan Sahara. Classification and description (J. Zipfel, MPI): the meteorite is partly covered with a brownish fusion crust; fresh surfaces are gray to dark gray; matrix is well consolidated; clasts include subophitic and fine-grained to microporphyritic impact-melt breccias, granulitic fragments, intergranularly recrystallized anorthosites, and mineral fragments; chemical and O isotope composition is characteristic of lunar highland meteorites (Zipfel et al., 1998b); abundances and composition of noble gases do not suggest a pairing with DaG 262 (Scherer et al., 1998b). For further details, see Zipfel et al. (1998b). Type specimen and two polished sections are with the MPI; main mass with finder.
