Sedimentological time-averaging and $$^{14}$$C dating of marine shells

Fujiwara, Osamu; Kamataki, Takanobu*; Masuda, Fujio*

Nuclear Instruments and Methods in Physics Research B, 223-224, p.540 - 544, 2004/08

The radiocarbon dating of sediments using marine shells involves uncertainties due to the mixed ages of the shells mainly attributed to depositional processes also known as sedimentological time-averaging. This stratigraphic disorder can be removed by selecting the well-preserved indigenous shells based on ecological and taphonomic criteria. These criteria on sample selection are recommended for accurate estimation of the depositional age of geologic strata from 14C dating of marine shells.
