Writeup from MB 102:

Northwest Africa 6013 (NWA 6013)

(Northwest Africa)

Purchased: 2009 Oct 28

Classification: HED achondrite (Diogenite, olivine)

Petrography: (K. Metzler, IfP) Coarse-grained ultramafic rock consisting of cm-sized domains that are dominated by olivine and pyroxene, respectively. The modal abundances of these subunits are about 50 vol% each. The transitions between them are blurred and the overall texture gives the impression of a metamorphic rock. In pyroxene-rich domains olivine occurs poicilitically enclosed in pyroxene crystals. Chromite grains with sizes up to several mm can be found. Troilite and metallic iron are minor constituents. Possibly paired with NWA 5480.

Geochemistry: Chromite: Cr/(Cr+Al)=0.79-0.84; Mg/(Mg+Fe)=0.18-0.29; TiO2=0.5-0.7 wt%

Classification: Hartzburgitic diogenite
