Abstract
The Kakoulima complex is a tholeiitic layered intrusion more than 1000 m thick, formed at the base by dunites and wehrlites topped by gabbros, mainly noritic. The small range of cryptic layering and the vertical geochemical evolution result from the emplacement of a cumulative pile, the differentiated liquids being restricted to scarce marginal dolerites. The relations with the doleritic sills of Western Guinea and the Central Atlantic rifting are discussed. There is an abridged English version. -English summary
