COMPLETE SLICE OF THE SINGULAR GUJBA METEORITE
Achondrite – bencubbenite
Yobe, Nigeria
This is a complete slice with characteristic nodules of metal and silicate in ample evidence. The sample shows a NE-SW alignment of nodules, a result of impact compression. Modern cutting.

Lot Essay

On April 3, 1984 at 6:30 P.M., a large mass burst into Earth’s atmosphere and became a blazing fireball over northeastern Nigeria. The meteorite landed in a cornfield, and the local citizenry broke the meteorite into numerous pieces and carried them away as talismans. Gujba is an exceedingly exotic coarse-grained bencubbinite — of which only a handful are known — and it’s the only observed bencubbinite fall. It is also pristine — the bencubbinite least affected by subsequent impact-induced brecciation and crushing. Gujba is made up of large ellipsoidal metal nodules and even-larger silicate nodules consisting of fine-grained fan-like arrays of pyroxene. It also contains some mineral grains formed at high shock pressure. Gujba is believed to have formed within an impact plume caused by a cataclysmic collision on a chondritic asteroid billions of years ago. Among the most beautiful and unusual-looking meteorites known, Gujba is an artifact from the early history of our solar system.
