The fluctuations are recorded by variations in lava chemistry along a 40 km long profile across the ridge. The temporal relations of the basalts were accurately restored using magnetic microanomalies. We report on the occurrence of ancient lavas enriched in incompatible elements whereas on‐axis samples are typical normal mid‐ocean ridge basalts. The enriched lavas are symmetrically distributed on either side of the ridge, implying that enriched melts reached the seafloor at intervals of about 150–200 kyr. This periodicity is viewed as a characteristic time scale in the aggregation processes of the melts produced from a heterogeneous mantle source. Geochemical variations of zero‐age mid‐ocean ridge basalts may primarily reflect such periodic processes rather than the spatial distribution of mantle heterogeneities.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1380004236853204227","@type":"Researcher","foaf:name":[{"@value":"Carole Cordier"}],"jpcoar:affiliationName":[{"@value":"Domaines Océaniques, UMR 6538 Université Européenne de Bretagne, Université de Brest, IUEM, CNRS  Place N.
