Writeup from MB 106:
Northwest Africa 11296 (NWA 11296) (Northwest Africa) Purchased: 2016 Classification: Ordinary chondrite (L6) History: A stone weighing 53 g was found in Morocco in 2016. David Holden acquired the sample from a meteorite prospector in Erfoud 2016. Physical characteristics: The oriented stone has a dark brown weathered fusion crust with rollover lipping and a flattened triangular shape. The interior of the stone is tan to orange, shows chondrules and fresh and weather flakes of metal. Petrography: Description and classification (A. Love, App): Sample is dark-orange in color and displays a recrystallized chondritic texture composed of indistinct chondrules with an average diameter of 808 μm, n=48 set within a recrystallized matrix. All Ca-poor pyroxene is orthorhombic and accessory apatite is present. FeNi metal comprises ~ 2 vol% of the specimen. Geochemistry: Olivine: Fa23.2±0.2 N=6; Low-Ca pyroxene: Fs19.3±0.4Wo1.5±0.3 N=6. Classification: Ordinary Chondrite (L6, S6, W2). Mineral compositions suggest this is an L chondrite. Specimens: An endcut and one slice weighing 10.63 g, and a polished thin section are currently on deposit at App. David Holden has the main mass. | ||||||||||||||||||||||||||||||||
