The Storøya Group has previously been interpreted as representing ocean island volcanism closely connected to the oceanic lithosphere material of the Leka ophiolite. New geochemical data indicate that the Storøya volcanites alternatively may be interpreted as formed in an oceanic rift environment and thus constitute an integral part of the Leka ophiolite complex. lf so, this oceanic crust represents an 'anomalous' ridge segment.
