Major and trace elements and Sr-Nd-Hf-Pb isotope data for the core samples of U1437 IODP Exp.350, and the modeling results of magma genesis

This dataset presents major and trace element concentrations and Sr-Nd-Hf-Pb isotope ratios for the core samples from the site U1437 IODP Exp.350. The modeling results of magma genesis by using Arc Basalt Simulator v.4 (ABS4) coded by Kimura et al. (2014) are also presented. IODP Site U1437 is located in the Izu rear-arc region, approximately 330 km west of the Izu-Bonin trench axis. The oldest four units (Units IV through Unit VII) include volcaniclastic sediment and in-situ hyaloclastites. They have ages of about 6–15 Ma, shortly after cessation of Shikoku backarc basin opening.
