Achondrite (lunar, granulitic breccia)

History: Found in 2005 and purchased by Stefan Ralew in January 2007 from a dealer in Quarzazate, Morocco.

Physical characteristics: A single, broken, irregular conical stone (606 g) partially covered by translucent, pale greenish fusion crust and with a pale gray-brown interior (Fig. 2).

Petrography: (A. Irving and S. Kuehner, UWS) Fine-grained recrystallized breccia composed of larger plagioclase grains (converted partially to maskelynite) poikilitically enclosing very small grains (mostly 30-80 microns) of low-Ca pyroxenes, olivine, Ti-chromite, ilmenite, troilite and metal.

Mineral compositions and Geochemistry: Olivine (Fa40.4-58.8, FeO/MnO = 91-100), plagioclase (An96.1-98Or<0.1), pigeonite (Fs32.0-64.5Wo9.5-13.1, FeO/ MnO = 51.1-62).

Classification: Achondrite (lunar, granulitic breccia). This stone is paired with NWA 3163 (Irving et al. 2006) and NWA 4483; in combination these specimens evidently represent naturally broken pieces from a crusted lunar meteorite weighing at least 2448 g. Specimens: A total of 20 g of sample and one polished mount are on deposit at UWS. Ralew holds the main mass.

Submitted by: A. Irving, UWS.
