For Sale IconNWA 4664 Polymict Diogenite Meteorites for Sale

Location: Northwest Africa, exact location unknown.

Found: Purchased in 2006

Classification: Polymict diogenite breccia

Description: History and Physical characteristics: Many stones that weigh ~20 kg were purchased in Rissani, Morocco, in July 2006 by A. Aaronson and are part of a large strewn field in which at least 30 kg have been recovered. Petrography: (T. Bunch and J. Wittke, NAU) A moderately shocked diogenite cataclastic breccia. Samples range from very matrix-rich to those that are matrix-poor and are composed of closely packed clasts. Mineral modes (vol%): orthopyroxene = 92, olivine = 4, plagioclase = 2, augite = 2, chromite and FeS = 1. Trace amounts of silica and metal are also present. The sample has at least two lithologies: one contains orthopyroxene with lowest FeO and without olivine; the other contains olivine with slightly more FeO-rich orthopyroxene. Orthopyroxene grains show minor amounts of shock lamellae and well-developed undulatory extinction. Plagioclase is partially isotropic. Mineral compositions and Geochemistry: Orthopyroxene (Fs17.8-23Wo1.1-2.8; FeO/MnO = 30-37), olivine (Fa24.1-32.6; FeO/MnO = 52-56), plagioclase (An79), chromite (Cr/(Cr + Al) = 0.67).
