Gujba Meteorite – Rare Carbonaceous Chondrite from Nigeria
The Gujba meteorite is a rare carbonaceous chondrite of the CBa group, also known as a bencubbinite. It fell on April 3, 1984 near the village of Bogga Dingare in Yobe State, Nigeria. Witnesses described the event as a bright fireball moving west to east, followed by an explosion. The meteorite landed in a cornfield, where locals broke it into several pieces and took them as talismans. The exact original weight of the meteorite is unknown but is estimated to be around 100 kg.
Composition and Formation of the Gujba Meteorite
Gujba consists of large ellipsoidal metallic and silicate nodules, with some silicate nodules containing fine-grained fan-shaped pyroxene aggregates. It is believed to have formed as a result of a cataclysmic impact on a chondritic asteroid billions of years ago, which created an impact plume from which the meteorite condensed.
