Detached intra-oceanic arcs containing continental basement rocks and stationary intra-oceanic arcs where back-arc spreading is absent display intermediate or equivocal relations. The significance of the difference in K-h correlation for continental margin and intra-oceanic magmatic arcs is uncertain but should be taken into account by theories for the petrogenesis of arc magmas.
