Franceville basin

The Franceville Basin is a 1.6–2.1 billion year old sedimentary basin in Gabon. It contains unmetamorphosed sediments. It is notable for containing the Francevillian Biota, which are possibly the oldest multicellular life known. A natural fission reactor formed there about 1.8 - 2.1 billion years ago.
