Northwest Africa 11080 (NWA 11080)

(Northwest Africa)

Purchased: 2016

Classification: Carbonaceous chondrite (CV3)

History: A stone weighing 91.23 g was found in Morocco in 2010. John Sinclair and J. Donald Cline acquired the sample from a meteorite prospector in Erfoud, 2015.

Physical characteristics: The windowed stone is dark gray, irregular in shape and has visible red-colored chondrules surrounded by black rims. The stone lacks fusion crust.

Petrography: (A. Love, App): Sample displays chondritic texture composed of chondrules, AOAs and CAIs in a mottled, light grey and dark opaque matrix (35 vol%). Most chondrules are defined and have an average diameter of 630.7 μm (69-2578 μm, n=187). Porphyritic chondrules have turbid to recrystallized mesostasis. A 3.2-mm type B CAI containing melilite, spinel, hibbonite and fassaite dominates a portion of the thin section. Larger chondrules (~1 mm dia.) are light red in color in plain light and are surrounded by darker regions composed of fine-grained, opaque clastic matrix devoid of sulfides. Matrix surrounding unoxidized chondrules contains abundant coarser grained sulfides.

Geochemistry: (A. Love, App) Fa15.1±18.1 (0.5-51.8), Fe/Mn=52.2 N=38; Low Ca pyroxene Fs2.0±0.7Wo1.8±1.2, N=13.

Classification: Carbonaceous Chondrite (CV3, S3, W2)

Specimens: PARI holds the main mass. One slice and several fragments weighing 18.43 g and one polished thin section are on deposit at App.
