Geology of Benin

The geology of Benin in West Africa broadly includes the north-northeast trending Proterozoic Dahomeyide orogen in the north and a range of Cretaceous to Holocene sedimentary rocks in the south. Neogene alluvial deposits extend across Benin’s northeastern border with Niger.[1]

In addition to artisanal gold mining, geological materials for industry and construction are worked. Benin also has relatively small reserves of crude petroleum and natural gas which remain (as of 2009) unexploited.[2]
