Writeup from MB 109:

Northwest Africa 13096 (NWA 13096)

Morocco

Purchased: 2014 Feb

Classification: Ordinary chondrite (H6)

History: Purchased from a Moroccan dealer in 2014

Physical characteristics: Nearly complete fusion crust, cut by deep cracks. Saw cut reveals a grayish-green interior with a number of small chondrules visible and relatively few bright metal and sulfide grains.

Petrography: Numerous moderately distinct to poorly delineated chondrules are observed, approximately 200-800 μm in size. Plagioclase grains are 50-200 μm. Large kamacite and taenite grains are abundant and highly oxidized. Cut by numerous terrestrial Fe-oxide beins. Minor chromite is also observed.

Geochemistry: Olivine Fa19.1±0.3, Fe/Mn= 36.4±2.4 n=10; low-Ca Pyroxene Fs16.7±0.2Wow1.74±0.06, Fe/Mn= 22.1±0.9 n=10; Taenite Fe= 92.0±0.3, Ni= 6.4±0.3, Co=0.51±0.04 wt%, n=3.

Classification: Ordinary chondrite (H6), weathering W3

Specimens: 31.6 g and an epoxy probe mount on deposit at UAz. Fredric Stephan holds the main mass.
