Northwest Africa 5667 was initially purchased
as a 396g stone from Morocco during 2008. The following year a
few other stones were purchased by the same buyer bringing the
Total Known Weight to just 1080g including the initial stone.
The meteorite was classified as an L3 Breccia with a Shock
Rating of S2.
It was obvious that NWA 5667 was fresh, but
on slicing... this meteorite would turn out to be one of the
freshest chondrites found in Northwest Africa to date. In fact
it is actually one of the freshest L3 chondrites ever found
anywhere in the world including falls with a clearly very short
It is a very distinctive chondrite with a
bright white to blue/grey colour covered in rich black fusion
crust. Chondrules are distinctly crisp with varying sizes and
shapes. Some slices of this meteorite which also display a
pale-grey breccia lithology which is not quite as abundant with
chondrules. One of the other interesting features are the
pockets of troilite (FeS) throughout the stones. The slice below
has one of these at centre-right near the outer edge. The other
obvious feature of this specimen is the large black inclusion
which appears to be a shock-melt pocket.
Since NWA 5667 was initially studied, several
other stones have been found which may be paired including
NWA 5701 and NWA 6168. A slice of NWA 5701 is pictured
below for comparison.
