Phlogopite stability and the 87Sr/86Sr step in basalts along the Reykjanes Ridge

Nature volume 254, pages 404–406 (1975)Cite this article

Abstract

THE relatively sharp step in the 87Sr/86Sr ratio within basalts midway along the Reykjanes Ridge may reflect the breakdown of titaniferous phlogopite during variable fusion of an essentially homogeneous phlogopite-lherzolite upper mantle, extending beneath both Iceland and the submarine parts of the Mid-Atlantic Ridge.
