NWA 1068 (SNC - Shergottite) - Unusual Inclusion
NWA 1068 was found in the Sahara Desert
during April 2001 and was classified as one of the rare SNC
Martian meteorites. Specifically, it is a Basaltic Shergottite
with a Total Known Weight of 576.77g. However, since this
initial find, many other paired fragments have been found and
classified under different NWA numbers. The partslice below
(27mm x 18mm x 2mm) is from the first 522g mass which was also
dubbed 'Louise Michel'. The NWA 1068 specimens are generally a
greenish-brown colour, partially coated by desert varnish and
some cracks are filled with terrestrial calcium-carbonate. Thin
shock veins and small melt pockets are also abundant throughout
this meteorite. Some of these features can be seen in the photographs
below. There is also an interesting and unusual inclusion in
this partslice. Within what appears to be a small dark melt
pocket on the left are smaller spherules of different material
which are approximately 0.5mm ± 0.15mm. They seem to be quite
out of place in comparison to the rest of the meteorite. The top
spherule appears to be a fragment from a larger one (bottom?)
while the centre one is more complete with the bottom one being
around 3/4 complete. This is Meteorites Australia specimen
number MA.CS.06.0003.
