Most sections drilled by the Deep Sea Drilling Project contain hiatuses. The sedimentary recycling implied by these hiatuses can be modeled if the proportion of surviving sections of a given age is representative of the mass of sediments of that age which remain beneath the deep-sea floor. The linear recycling model of Garrels and Mackenzie [1] overestimates the proportion of surviving Neogene sections and underestimates those of the Paleogene, suggesting that one of the underlying assumptions has been violated. A new model, in which the observed frequency of hiatus durations is used to modulate the probability of erosion with increasing age, fits the observations much better. Deviations from the general trend can be modeled by varying the mass of sediment deposited per million years and the area of non-deposition by factors of 4 and 20 respectively. The model permits a quantitative comparison of maxima and minima in surviving sections through the Cenozoic, free of the effect of an overall decline in the proportion of such sections with increasing age.
