NWA 2046

I bought this stone in Morocco in September 2003. It was a single stone that weighed only 63 grams. Here is the complete classification data submitted to the nomenclature committee.

Northwest Africa 2046, Morocco, 2003
Martian basalt (shergottite)

A 63g complete and partially crusted stone was purchased in Rissani, Morocco, September 2003. Classification and mineralogy (J. Wittke and T. Bunch, NAU; A. Irving and S. Kuehner, UWS): olivine-orthopyroxene-phyric basalt; subhedral to euhedral olivine phenocrysts (< 2.2 mm) are strongly zoned from cores of Fa15.5 to rims of Fa 47.9and subhedral to euhedral orthopyroxene pheoncrysts (<2.1 mm) are zoned in a chaotic manner from cores of Fs 17.7Wo2.5 to  pigeonite rims of Fs39.0Wo12.5. Interstitial maskelynite is zoned from cores of An74.4Or0.1to rims of An62.3Or1.1. Accessory minerals include chromite, Cr-uvöspinel, ilmenite, pyrrhotite, merrillite, chlorapatite, and fayalite that mantles  some ilmenite. Trapped melt inclusions in olivine contain Al-pigeonite, Al-diopside, pleonaste and glass. Large opx phenocrysts show preferred orientation; olivine phenocrysts are weakly oriented and tend to occur in clusters. The stone has a 1ö2 mm weathering rind; interior is very fresh. Specimens: 12.2g, NAU; main mass, Strope.

I own half the mass and Jim Strope owns the other half, which he is keeping intact, so there is only 15 grams available for private purchase. This is it.  These are the last pieces I have for sale.
