Figure F14. Sr and Pb isotopic variability at Detroit Seamount (Huang et al., 2005). Data points are for ODP Sites 883 and 884 and Sites 1203 and 1204. Detroit Seamount lavas are distinguishable from both Hawaiian Islands shield lavas and current East Pacific Ridge MORB compositions but are similar to posterosional lavas and lavas erupted on the flexural arch north of Oahu.
