Writeup from MB 109:

Northwest Africa 13095 (NWA 13095)

Morocco

Purchased: 2014 Feb

Classification: Ordinary chondrite (L6)

History: Purchased from a Moroccan dealer in 2015

Physical characteristics: 328g single piece that has a brownish red fusion crust. The fusion crust is broken suggesting weathering of the piece. A saw cut reveals a moderate amount of bright speckled metal and sulfieds. There is a large dark area lacking metals and sulfides.

Petrography: (T.Burd and E. Ratliff, UAz) There are plagicase grains to 110 microns. Extensive recrystallization has taken place with indistinct chondrules present. Chromite, taenite, and apatite present. Troilite and kamacite also observed in a partially oxidized state. Sample cut by many iron-oxide weathering veins.

Geochemistry: Mineral compostions and geochemistry: Olivine Fa25.2±1.0, Fe/Mn=48.7±3.9, n=10; low-Ca pyroxene Fs21.1±0.6Wo1.6±0.3, Fe/Mn=29.1±2.2, n=10; Kamacite Fe=92.9±0.4, Ni=6.4±0.3, Co0.65±0.04 wt%, n=3

Classification: Ordinary Chondrite (L6), Weathering Grade W3.

Specimens: 27.4 g and an epoxy probe mount on deposit at UAz. Fredric Stephan holds the main mass.
