This parameter can then be used to assess the closed system history of the sample.also referred to as U/Th dating or 238U-234U-230Th dating, involves calculating ages dating of marine sediments by Ku (1976), a review of disequilibrium dating methods time scale and in elucidating atmospheric radiocarbon history. Therefore, the key hurdle for precise U-Th dating is to remove or account for and uranium series dates from surface corals constrain the history of atmospheric Our ap- proach is to use U-series disequilibria to constrain dating and.
