Writeup from MB 106:

Northwest Africa 11294 (NWA 11294)

(Northwest Africa)

Purchased: 2011

Classification: Ordinary chondrite (H6)

History: A stone weighing 30.3 g was found in Morocco in 2011. David Holden acquired the sample from a meteorite prospector in Erfoud 2011.

Physical characteristics: The oriented stone displays a defined rollover lip and has an irregular shape and is covered (~60%) by a weathered brown fusion crust. The crust has several sand-filled cracks. The cut surface displays weather and fresh flake of metal and chondrules on the interior of the stone.

Petrography: Description and classification (A. Love, App): Sample shows a recrystallized chondritic texture composed of some distinct chondrules within a recrystallized matrix. Relict chondrules have an average diameter of 739 μm, n=14.

Geochemistry: Olivine: Fa18.7±0.2 N=6; Low-Ca pyroxene: Fs16.0±0.4Wo1.7±0.2 N=6.

Classification: Ordinary Chondrite (H6, S3, W2). Mineral compositions suggest this is an H chondrite.

Specimens: Three slices weighing 10.3 g and one polished thin section are on deposit at App. David Holden holds the main mass.
