THIS IS A LIFE TIME OPPORTUNITY TO OWN A PIECE OF MARS
This unique Martian Shergottite meteorite is officially classified & approved as
NWA 13038 and was discovered in Zouerat Mauritania in November 2019 &
classified by world renowned and profoundly respected Dr Anthony J. Irving and team at University of Washington
NWA 13038
This specimen is relatively fine grained (mean
0.4 mm) and
composed mainly of polysynthetically-
twinned, zoned clinopyroxene and
maskelynite with ac-
cessory ilmenite, ulvöspinel
(both Cr-bearing and
Cr-
free),
chromite (with Ti-rich lamellae and rims), pyrrho-
tite,
merrillite, chlorapatite and silica polymorph (see
Figure 2).
One large orthopyroxene grain (2.5 mm
across)
with a pigeonite rim was observed.

Northwest Africa 13038
(NWA 13038)
(Northwest Africa)
Purchased: 2019 Nov
Classification: Martian meteorite (Shergottite)
History
: Purchased by Mbark Arjdal from a dealer in Zouerat, Mauritania in November 2019.
Physical characteristics
: A single stone (587 g) partly covered with black fusion crust and with several broken surfaces revealing the fresh light gray interior.
Petrography
: (A. Irving,
UWS
and P. Carpenter,
WUSL
) Relatively fine grained (mean grainsize 0.4 mm) and composed predominantly of polysynthetically-twinned, zoned clinopyroxene and maskelynite with accessory ilmenite, ulvöspinel (both Cr-bearing and Cr-free), chromite (with Ti-rich lamellae and rims), pyrrhotite, merrillite, chlorapatite and silica polymorph. One large orthopyroxene grain (2.5 mm across) with a pigeonite rim was found in the studied thin section. Sparse patches of pale glassy, vesicular impact melt and a thin darker veinlet of similar material were observed, as well as minor secondary calcite (as thin veinlets and vesicle linings).
