Northwest Africa 3008 Morocco Found 2002 Primitive Achondrite (acapulcoite) A single black stone of 157 g with fusion crust was found by Moroccan nomads and sold in Morocco. Mineralogy and classification (J. Schlüter, Hamburg): Granoblastic texture with grain sizes in the range of 100 – 300 μm. Mean olivine (Fa12.7±0.3), mean orthopyroxen (Fs13.0±0.1) and kamacite (6.61 wt.% Ni, 0.27 wt.% Co) are the main components; tiny metal plebs occur in olivine and orthopyroxene; rich in plagioclase (mean Ab79.0, range Ab76.7-83.4; mean An18.26, range An13.3-20.5; mean Or2.8, range Or2.2-3.3) and troilite. Minor phases are clinopyroxene (mean Cr2O3, 1.46 wt.%), chromite, fluorapatite and merrillite (Mg end-member). Nobel gases (L. Schultz, Mainz); the exposure age of 6.8±0.6 Ma is within the acapulcoite/lodranite range. Weathering grade: W2, shock stage: S1.
