Writeup from MB 106:
Northwest Africa 11293 (NWA 11293) (Northwest Africa) Purchased: 2016 Classification: Ordinary chondrite (H6) History: 1 stone weighing 39.4 g was found in Morocco in 2016. David Holden acquired the sample from a meteorite prospector in Erfoud 2016. Physical characteristics: Sample is a triangular-shaped oriented stone (with rollover lipping), dark brown weathered fusion crust (covers about 40% of stone) with a few shallow regmaglypts, moderately magnetic. Petrography: Description and classification (A. Love, App): Poorly-defined chondrules with an average diameter of 656 μm (n=55) in a recrystallized matrix. Porphyritic chondrules contain turbid-recrystallized mesostasis. Geochemistry: Olivine: Fa17.4±0.2 N=6; Low-Ca pyroxene: Fs15.2±0.2Wo1.1±0.1 N=6. Classification: Ordinary Chondrite (H6, S3, W3). Mineral compositions suggest this is an H condrite. Specimens: One polished thin section and a 8.20 g type specimen are on deposit at App. David Holden holds the main mass. | ||||||||||||||||||||||||||||||||
