Writeup from MB 100:

Northwest Africa 6819 (NWA 6819)

Morocco

Purchased: 2009

Classification: HED achondrite (Diogenite, olivine)

Petrography (P. Warren, UCLA): Mode: ~90% orthopyroxene, 10% olivine, traces of metal, Cr-spinel and FeS. The texture is brecciated, but some grains appear to retain nearly their original outlines, and these tend to be equant and range up to 2.5 mm for olivine and 4 mm for orthopyroxene.

Geochemistry: Metals are nearly pure Fe (Ni not detectable by EDS). Orthopyroxene FeO/MnO averages 27. Cr-spinel has 30 wt% FeO, 17 wt% Al2O3, 3.1 wt% MgO.
