Writeup from MB 105:

Northwest Africa 10596 (NWA 10596)

Morocco

Purchased: 2014

Classification: HED achondrite (Eucrite, brecciated)

History: A sample of 58.6 g was purchased in 2014 in Dakhla, Morocco, from a meteorite dealer.

Petrography: (A. Bischoff, IfP) Different basaltic and granulitic eucrite clasts and mineral fragments are embedded within a brownish groundmass. The matrix represents a crystallized melt mainly consisting of small pyroxene and plagioclase crystals. This texture is typical for melt rocks formed by impact processes.

Geochemistry: Mineral compositions and geochemistry: (M. Patzek, A. Bischoff, IfP): Pyroxenes and plagioclase of the lithic clasts were analyzed. Low-Ca pyroxene: Fs57Wo8 (Fs53-61Wo3-14). Ca-pyroxene: Fs29Wo41 (range Fs27-33Wo39-42). Plagioclase: An 92.3±1.5 (An88-94; n=13). Fe/Mn of all pyroxene: 33±3. All are typical values for eucritic samples.

Classification: Brecciated eucrite (clast-rich melt rock)
