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.补充材料：本研究中分析的锆石U-Pb同位素数据。不确定度以2σ置信水平给出。百分谐和度（%conc）= 100 × (²³⁸U–²⁰⁶Pb年龄)/(²³⁵U–²⁰⁷Pb年龄)，该指标用于衡量²³⁸U–²⁰⁶Pb与²³⁵U–²⁰⁷Pb年龄之间的谐和性。阴影标注的为不协调数据，此类数据未被纳入概率密度图或直方图。
