摘要：
The Kakoulima complex is a tholeiitic layered intrusion more than 1,000 m thick, formed al 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.
