Closed system age interpretations for U-Th dated samples, IODP Expedition 325

Ages are presented in thousands of years before AD 1950 so as to be comparable to calibrated radiocarbon ages. [234U/238U]i is [234U/238U] extrapolated back to the time of coral growth.

年代以公元前1950年的千年来表示，以便与校准后的放射性碳年代相一致。[234U/238U]i值被外推至珊瑚生长的时代。
