Abstract
The dolerites which crosscut the Congo craton in South-West Cameroon b elong to two distinct episodes of pre-orogenic extensions. The first e pisode, ante-Eburnean, displays the geochemical characteristics of bac k-are basin tholeiites and of greenstone belt volcanics, and is linked to the opening of the Nyong Palaeoproterozoic basin. The second episo de, ante-Pan-African, has the composition of typical continental thole iites and is related to the formation of the Yaounde Neoproterozoic ba sin.
