Writeup from MB 110:

Northwest Africa 6414 (NWA 6414)

Morocco

Purchased: May 2010

Classification: HED achondrite (Eucrite, polymict)

History: The stone was purchased by Fabien Kuntz in 2010 in Agadir, Morocco

Physical characteristics: Single wind-polished stone weighing 432 g. Cut surface is pale with visible clasts and mineral fragments.

Petrography: (A. Jambon UMPC; J. Mitchell, University of Plymouth, UoP) Breccia predominantly composed of fine mineral fragments of low- and high-Ca pyroxene and plagioclase, but also contains a variety of subophitic and granulitic basaltic lithologies (<3 mm clasts) and quenched melt clasts. A silica phase is common, as are accessory ilmenite, chromite, and troilite. Fe-metal is rare.

Geochemistry: Low-Ca pyroxene Fs29.4-57.5 Wo4.36-10.0, mean Fs43.1Wo8.9 (n=36). High-Ca pyroxene Fs21.8-78.0Wo15.2-46.2, mean Fs45.4Wo32.6 (n=37). Plagioclase An82.5-76.4Or0.2-1.6, mean An92.7Or0.5 (n=40). Chromite Cr#84.2 (n=4). Bulk Fe/Mn 32.89. (EDS).

Classification: Eucrite (polymict)
