Description:  56.9 gram amazing full slice of Martian Shergottite meteorite NWA 10961. I rarely see slices of Martian meteorites this big or this beautiful. Martian meteorites were ejected by another meteorite impacting the surface of the Red Planet and hurling material from Mars to Earth.
Fit for any museum or private collection of exceptional taste, this 56.9 gram slice of Mars has excellent surface to mass ratio.
This Martian meteorite is part of the SNC group of Martian meteorites, and more specifically is known as a "Shergottite”. This shergottite in particular is known as NWA 10961.

Northwest Africa 10961 (NWA 10961)

(Northwest Africa)

Purchased: 2016 Sep

Classification: Martian meteorite (Shergottite)

History: Purchased by Ben Hoefnagels in September 2016 from a dealer in Taliouine, Morocco.

Physical characteristics: A single mass (2220 g) with a brown, weathered exterior. The fresh interior is mostly pale green with small dark brown patches and black grains visible.

Petrography: (A. Irving and S. Kuehner, UWS) Poikilitic texture. Large, twinned, essentially unzoned pyroxene oikocrysts (with undulose extinction) enclose chadacrysts of olivine (some brownish in thin section) and Cr-rich chromite. Very sparse maskelynite (~2 vol.%) occurs as interstitial grains. Other accessory minerals are Ti-bearing chomite, ilmenite and rare Mg-merrillite. Pockets of dark, quenched shock glass are present.

Geochemistry: Olivine (Fa29.5-31.2, FeO/MnO = 41-46, N = 3), orthopyroxene (Fs19.4-20.7Wo2.7-3.6, FeO/MnO = 20-28, N = 3), augite (Fs13.0-13.8Wo38.2-35.0, FeO/MnO = 22-24, N = 2), maskelynite (An53.8-55.6Or1.1-1.0, N = 2).

Classification: Martian meteorite (shergottite, poikilitic, ultramafic).

Specimens: 22 g including two polished thin sections at PSF; remainder with Mr. B. Hoefnagels.
