Seperate entry from the Meteoritical Bulletin:

History: The meteorite was found by an anonymous finder in Northwest Africa and bought by the main mass holder in Quarzazate, Morocco.

Physical characteristics: One fragment almost completely covered with fusion crust weighing 137 g was found.

Petrography: (A. Greshake, MNB). The meteorite exhibits a spherulitic texture of dominantly lath-shaped plagioclase, pyroxene, and skeletal ilmenite. Olivine occurs as single larger crystals often containing Ti-rich chromite inclusions. Plagioclase is Ca-rich and has been completely transformed into maskelynite during shock metamorphism; pyroxene is compositionally zoned Ti-rich pigeonite and augite. Minor phases include FeNi-metal and troilite.

Geochemistry: Plagioclase (An92.6-96.5), olivine (Fa26.3-27.2; FeO/MnO = 73-92), pyroxene (Fs25.1-58.7Wo13.2-34; FeO/MnO = 42-76).

Classification: Achondrite (Lunar basalt); exstensive shock, minimal weathering.

Specimens: A total of 21.1 g plus one polished thin section are on deposit at MNB. Ralew holds the main mass.

Meteorite name:

NWA 3170

Type:

Achondrite, lunar ferroan gabbro breccia

Location:

Sahara, Northwest Africa

Date of find:

2007

Tkw:

60 g

Specimen weight:

4.316 g

Description:

Full slice, polished, 38 x 19 x 2.5  mm


Fresh monomict breccia consisting of ferroan gabbro clasts and related debris.  Composed mainly of olivine (Fa29.6-39.9, FeO/MnO = 82-116), various clinopyroxenes and anorthite, with accessory fayalite, silica polymorph, ilmenite and minor K-Ba-feldspar.  Clinopyroxenes (both as individual grains and regions within zoned grains) comprise pigeonite (Fs42.3Wo11.9, FeO/MnO = 79), subcalcic augite (Fs28.7Wo26.2, FeO/MnO = 57) and subcalcic ferroaugite (Fs64.4-78.8Wo26.3-26.2, FeO/MnO = 78-93).  Notable in this specimen are grains composed of symplectitic intergrowths of hedenbergite+fayalite+silica, which presumably represent subsolidus breakdown of original pyroxferroite.  Orthopyroxene is absent and no basaltic-textured clasts are present.
