Diatom analyses, pollen analyses, and radiocarbon dating have been used to establish the Holocene shoreline displacement on the peninsula Frosta in Trondheimsfjorden, Norway. Great importance has been attached to the aspect of dating, and 23 radiocarbon dates together with 8 pollen analytical dates are
presented. Both the NaOH soluble-(SOL) and the NaOH insoluble fraction (INS) have been radiocarbon dated. Possible sources of error associated with the radiocarbon method in the investigated area are discussed in relation to the pollen analytical dates. The hyperbolic form of the shoreline displacement
curve, which is based on 10 dated marine/lacustrine boundaries, shows a continual regression from Younger Dry as to the present.
