Gao–Guenie Meteorite Slice from West Africa - 0.20 ounce Specimen


The Gao–Guenie meteorite is a Olivine-Bronzite Chondrite, H5 meteorite that fell on Burkina Faso, West Africa, on March 5, 1960 at 17:00 (local time). The fall was composed of a large number of fragments and it is one of the largest observed meteorite showers in Africa to date.

The meteorite, prior to 1999, was formerly known as Gao and Guenie meteorites, however, once evaluated as the same meteorite event, they now share the collective name Gao–Guenie. Scientists believe there were three separate detonations during its descent, meaning the searing friction and heat of entry into the atmosphere caused the meteorite to explode into fragments, continued their decent, heating and fragmenting a second time, and then again, for a third time.

Several thousands of stones rained down over a triagular area of about 70 square kilometers (27 sq mi) and the sound of the fall could be heard 100 kilometers (62 mi) away. Eyewitnesses said that some trees were broken and hen houses destroyed. The largest stones recovered weigh up to 10 kilograms (22 lb).
