Abstract

<strong>Here we present a new data set from ten islands of the hot-spot related Galapagos Archipelago. That includes zircon U-Pb geochronology and δ18O - εHf(t) isotope geochemistry and whole rock geochemistry. The methodology includes different analytical technics like SHRIMP II, LA-MC-ICPMS, ICP, and XRD.</strong> <strong>This repository contains the following files:</strong> <strong>Table S1. </strong>LA-MC-ICPMS Lu-Hf isotope data of Galápagos zircons measured at Hong Kong University. <strong>Table S2. </strong>LA-MC-ICPMS Lu-Hf isotope data of Galápagos zircons measured at Frankfurt University. <strong>Table S3.</strong> Major and trace element concentrations for Galápagos samples. <strong>Table S4. </strong>Oxygen isotope ratios for Galápagos zircons. <strong>Table S5. </strong>Thermo-mechanical properties of the rock phase. <strong>Table S6.</strong> List of the numerical experiments. <strong>Table S7:</strong> List of the experiments used to calibrate the permeable boundary condition. <strong>Table S8.</strong> (A) Hf Isotope Ratios in Galapagos Lavas (After (Blichert-Toft &amp; White, 2001). (B) Oxygen isotopic ratios of plagioclase separates from Galapagos lavas and xenoliths (Geist et al., 1998). (C) Oxygen isotope compositions of olivine grains from subaerial lavas (Peterson et al., 2019). (D) Hf Isotope Compositions (±2s) of Submarine Ridges in the Panama Basin and of CLIP (Caribbean Large Igneous Province) rocks (Geldmacher et al., 2003). Movie S1
