Neodymium isotopic evidence for Galapagos hotspot—spreading centre system evolution

Nature volume 306, pages 654–657 (1983)Cite this article

Abstract

Nd and Sr isotope variations along the Galapagos spreading centre support Morgan's preferential subcrustal flow channel connecting the Galapagos mantle plume with the northeastward migrating ridge axis. Decoupling of La/Sm and Nd isotope variations near 91° W further suggests that basalts are derived from smaller degrees of melting and are deeper beneath this elevated part of the ridge.
