The Ntem complex corresponds to the northwestern border of the Congo craton in Southern Cameroon. It is bounded to the north by the Yaoundé Group which belongs to the Pan-African orogenic belt in Central Africa. The Ntem complex has been subdivided into three units: Ntem, Nyong and Ayna.
The Ntem unit contains the Bikoula BIF and comprises an intrusive series, a banded series and greenstone belts.
