Writeup from MB 103:

Northwest Africa 8048 (NWA 8048)

(Northwest Africa)

Purchased: 2013 Aug

Classification: HED achondrite (Eucrite)

History: Purchased in August 2013 by Aras Jonikas from a dealer in Morocco.

Petrography: (A. Irving and S. Kuehner, UWS) The specimen consists of a large fine-grained, granulitic eucrite clast with attached basaltic eucrite material. Both lithologies are composed of exsolved pigeonite and calcic plagioclase with accessory ilmenite, silica polymorph, troilite and Ni-poor metal.

Geochemistry: Pyroxene in the granulitic portion consists of exsolution lamellae of augite (Fs27.3-28.2Wo42.7-41.9; FeO/MnO = 29-32) within host orthopyroxene (Fs61.5-61.9Wo3.1-2.1; FeO/MnO = 30-31); in the coarser, ophitic material augite lamellae are Fs26.7Wo42.3 (FeO/MnO = 29) and host orthopyroxene is Fs58.0Wo4.3 (FeO/MnO = 32).

Classification: Eucrite.

Specimens: 22.2 g including a polished thick section at UWB. The remainder is held by Mr. A. Jonikas.
