Six meteorite falls have been recorded in various parts of Nigeria. The Uwet meteorite, from Uwet in Calabar Province is classified as a normal hexahedrite of the Braunau type with an approximate chemical composition of Fe14Ni. The Udei meteorite, from north of the Benue River near Makurdi, is classified as a mesosiderite. It is the only representative of this type in Nigeria and is comparatively rare elsewhere in the world. The two Git Git meteorites, from near Bogoro in the Lere District of Bauchi Province, and the Karewar meteorite, from Karewar in Katsina Emirate, are white chondrites. The Geidam meteorite, from Garau in the Zajibiri Village Unit of Geidam District, Bornu Province, is a typical chondrite with a moderately high proportion of iron-nickel alloy. The ratio of silicates to iron-nickel is of the order of 4 to 1. Only small pieces were recovered from a meteorite that was observed to break up at a great height over Adamawa Province and the Cameroons in November 1952. - V. S. N
