Northwest Africa 11087 (NWA 11087)

(Northwest Africa)

Purchased: 2013

Classification: Carbonaceous chondrite (CV3)

History: The stone was bought by Jean Redelsperger from Abdellah Afiniss in Agadir in 2013.

Physical characteristics: A crusted fragment. Cut surface reveals large chondrules and CAIs set in abundant dark brown matrix.

Petrography: Chondrules (average apparent diameter 990±340 μm, N=27) and irregular CAIs (to 2 mm) set in an abundant fine-grained iron-rich matrix. Opaques are mostly metal and sulfides, and their terrestrial weathering products.

Geochemistry: Olivine Fa range 0.4-50.4, average Fa11.5±14.9, PMD 102%, (N=7). Orthopyroxene Fs1.2±0.1Wo1.0±0.1 (N=2). Magnetic susceptibility log χ (× 10-9 m3/kg) = 3.43.

Classification: Carbonaceous chondrite (CV3). Reduced subgroup. Strong weathering.

Specimens: 10 g at CEREGE. Main mass with Jean Redelsperger.
