Writeup from MB 103:

Northwest Africa 8056 (NWA 8056)

(Northwest Africa)

Purchased: 2013 Aug

Classification: HED achondrite (Eucrite)

History: Two very similar stones (960g, 600 g) were purchased together in Temara, Morocco, by A. Aaronson, who provided portions of both stones as type material.

Petrography: (A. Irving and S. Kuehner, UWS) Fragmental breccia composed predominantly of gabbroic eucrite clasts in a sparse matrix of related debris. Minerals are exsolved pigeonite (with variable red-brown staining), calcic plagioclase (polycrystalline, birefringent), silica polymorph, ilmenite, Ti-rich chromite, Ti-poor chromite, troilite and minor secondary barite.

Geochemistry: Orthopyroxene host (Fs_60.1-62.3Wo_3.6-1.9, FeO/MnO =29-31), clinopyroxene exsolution lamellae (Fs_26.7-27.5Wo_43.4-42.0, FeO/MnO = 27-31).

Classification: Eucrite (polymict, gabbroic). Based on primary textures, shock features and style of weathering, this material is likely paired with NWA 7989 and NWA 8036.

Specimens: A total of 20.1 g including one polished thin section at UWB. The remaining material is held by Aaronson.
