Research data for: Sedimentary history and provenance analysis of the Sanbagawa Belt in eastern Kii Peninsula, Southwest Japan, based on detrital zircon U–Pb ages

Supplementary material: U–Pb isotope data for zircons analyzed in this study. Uncertainties are given at the 2σ level. %conc = 100 × (238U–206Pb age)/(235U–207Pb age) is the measure of concordance between 238U–206Pb and 235U–207Pb ages. Shading indicates discordant data, which were not included in the probability density plots or histograms.
