NWA 2624 (Ureilite) - 2.1g Slice with Pyroxene Megacrysts
The meteorite, NWA 2624 was a 241g single
stone found in two joining halves in North West Africa and
purchased in Erfoud, Morocco during 2004. This meteorite has
been classified as a rare Ureilite with a Shock Rating of S2 and
is also a very fresh specimen with a Weathering Level of just
W0/1. There were rumours of "Stony Pallasites" being found in
North West Africa over the past year or two and then NWA 2624
came onto the international market at the beginning of 2005
bringing those tales to fruition. It was initially thought that
these large crystals in the matrix were olivine but they have
actually been described as "Pyroxene Megacrysts". In just a few
of the thinner slices with larger Megacrysts, light is easily
able to pass through giving them a brilliant orange/yellow/green
colour. This specimen is a 2.10g Complete Slice and is part of the
Meteorites Australia Collection (MA.05.0001).
