The cause of the Bangui anomaly (the red or high magnetization region
situated over the Central African Republic) is controversial. In 1992 Girdler,
Taylor and Frawley (Tectonophysics, vol. 212, p.45-58) proposed that this
anomaly was produced by a large meteorite impact at 1 billion years
old. Others have suggested it results from a major fracturing of the crust
or the implacement of a large igneous body.
