The Kilabo meteorite
fell at 19:30 local time on July 21st, 2002 in Nigeria, Africa. Incredibly, this
was just several hours after the
Thuathe meteorite fell some
5000kms away on the other side of the African continent in
Lesotho. The Kilabo fireball was reportedly observed moving from
South to North during which two detonations were heard. Mr. Mallam Audu and several
neighbours in Kilabo heard the stone fall and later recovered
it. The meteorite was found in a small crater/depression measuring 35cm wide by
20cm deep in sandy soil. It had fragmented on impact into many
pieces, the largest of which was 2.2kg. Stones were recovered in
five villages in the region, with the largest piece found in
Kilabo. A Total Known Weight of approximately 19 kg was
recovered.
Kilabo has been classified as an Ordinary
Chondrite LL6, with a Shock Rating of S3 and a Weathering Level
of W0 (Unweathered). It is a Brecciated Chondrite with thin
black shock veins and coarse-grained diopside. Troilite (FeS)
is also abundant. Kilabo is characterised by its beautiful pale
ash-grey interior, richly contrasted by the unusually thin, striking black
fusion crust. There is a particular crisp delicateness to
Kilabo which generally isn't seen in other recent falls such as
Bensour,
Thuathe and
Oum Dreyga.
Many individuals from the Kilabo fall have a knobbly or
almost gentle wavy appearance. This may be from mid-stage
detonations during the fall which allowed sufficient time to
redevelop the rich black fusion crust but not enough to ablate a
smooth surface again. The specimens below are part of the Meteorites Australia
Collection.
