摘要：

Mt. Cameroon erupted simultaneously in March-April 1999 in two distinct places on its southwestern flank. A hawaiite (with An 83-76 plagioclase phenocrysts) and an alkali basalt (with Fo 84-80 olivine phenocrysts) have been simultaneously emitted respectively at 1 400 and 2 650 m of altitude a.s.l. The eruption of these co-magmatic lavas attests to the occurrence of a unique magmatic reservoir inside which the magma differentiation took place by crystal set-ring of denser mineral phases.
