Writeup from MB 106:

Northwest Africa 11414 (NWA 11414)

Morocco, Laayoun, (Northwest Africa)

Purchased: May 2014

Classification: Enstatite chondrite (EL6)

History: Collected by nomads in Western Sahara and purchased by Nicola Castellano at the Genova Mineral Fair in May 2014 from a Moroccan dealer.

Physical characteristics: A single piece weighing 53 g with no fusion crust.

Petrography: (V. Moggi Cecchi, G. Pratesi, S. Caporali, UniFi); A fine-grained texture, with a pyroxene-dominant matrix and minor plagioclase is visible in thin section. No relic chondrules are visible. The main opaque phases are kamacite and troilite, partially weathered to iron oxides. Blades of alabandite are occasionally visible in troilite. A classification as EL chondrite is suggested by the presence of alabandite, An content of plagioclase and Si content of kamacite;

Geochemistry: EMP (V. Moggi Cecchi, G. Pratesi, S. Caporali, UniFi) Orthopyroxene (Fs0.6En97.9Wo1.5), plagioclase (An15.4Or4.1); Si in kamacite = 0.7 wt.%, Ti in troilite = 6.4 wt.%

Classification: Enstatite chondrite (EL6); S1; W3

Specimens: A total of 11.0 g specimen is on deposit at Museo di Storia Naturale dell’Università di Firenze (MSN-FI). Castellano holds the main mass.
