I've added an additional data set for the Galapagos "hotspot" to an existing post:
Isotopic Dates from Global "Hotspot" Traces. Scroll to #1070646 - 12/11/07 11:34 AM.
The new data are from: O'Connor J. M., Stoffers, P., Wijbrans, J. R., and Worthington, T. J., 2007, Migration of widespread long-lived volcanism across the Galápagos Volcanic Province: Evidence for a broad hotspot melting anomaly? Earth and Planetary Science Letters, 263, 339-354, doi:10.1016/j.epsl.2007.09.007.In this kmz there is also a folder with K/AR dates from: W.M. White, A.R. McBirney and R.A. Duncan, 1993, Petrology and geochemistry of the Galápagos Islands: portrait of a pathological mantle plume, Journal of Geophysical Research, 98 , 19,533–19,563.
