Writeup from MB 106:

Northwest Africa 11048 (NWA 11048)

(Northwest Africa)

Purchased: 2005 Jun

Classification: Primitive achondrite (Acapulcoite)

History: Purchased from a Moroccan dealer at the mineral show in Sainte-Marie-aux-Mines, France.

Petrography: (K. Metzler, IfP) Recrystallized rock with abundant 120° triple junctions, consisting of low-Ca pyroxene, olivine, Ca-rich pyroxene, troilite, metallic Fe,Ni and plagioclase. Accessory phases are chromite and phosphates. Grain sizes of silicates mostly below 0.5 mm with some metal grains up to 1 mm.

Geochemistry: Mineral compositions and geochemistry: Olivine Fa10.8±0.2 (Fa10.6-11.1); n=8. Low-Ca pyroxene Fs10.4±0.1Wo1.9±0.6 (Fs10.3-10.6Wo1.1-2.8, n=8). Ca-rich pyroxene Fs4.6±0.4Wo43.2±1.2 (Fs3.9-5.1Wo41.4-45.0, n=9). Cr2O3 in Ca pyroxene 1.5 wt%. Plagioclase An16.8±0.7Or3.0±0.4 (An15.1-17.4Or2.3-3.6, n=8).

Classification: Acapulcoite, based on mineral chemistry and mean grain size of silicates.
