NWA 2385 (L3.8) - 9.2g Half Slice with Large Inclusion & Gold(?)
NWA 2385 was found in North West Africa during 2004 and has been
classified as an Ordinary Chondrite, L3.8. Only one stone
weighing 410g was discovered. The specimen below has an obvious
large inclusion at the top centre which I dubbed a "Matryoshka Inclusion"
in recognition of the famous Russian wooden dolls. It's an inclusion
within an inclusion within an inclusion! About 50%-60% of the
inclusion (chondrule?) appears to be in a semi-translucent crystal form.
The third photo shows (indicated by an
arrow) a small inclusion which appears like gold.
Gold has only ever been found in meteorites in minute
concentrations so even though the
colour and lustre makes it look like gold, this metallic mineral
is mostly likely of a sulphur origin. This would explain its
yellow/gold hue. This particular inclusion is about 1mm in size
but there are also several other similar sub-millimetre sized specks too. This
piece is part of the Meteorites Australia Collection.
