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.
