NWA 8160 is a fresh, rare, R5 meteorite--only 31 other R5's are known at this time, making this quite rare.  A single stone weighing 148 grams was obtained from the Sahara Desert.  Official classification was performed by Dr. Anthony (Tony) Irving of the University of Washington's Earth & Space Sciences department.

Only a handful of slices exist.  Specimen come enclosed in a protective case as pictured.

Petrography: (A. Irving and S. Kuehner, UWS) Fresh specimen containing some well-formed, mostly granular chondrules in a relatively coarse grained matrix containing Ti-bearing chromite, pentlandite, pyrrhotite and sodic plagioclase.

Geochemistry: Olivine (Fa39.4-40.0, N = 3), orthopyroxene (Fs29.4-30.5Wo0.8-1.4, N = 2), augite (Fs10.2-11.9Wo46.3-45.1, N = 2).
