Abstract

An intertidal organic deposit is described for Traigh Eileraig, Isle of Coll, Scottish Inner Hebrides. The organic sediments are overlain by sands containing marine diatoms. Radiocarbon dating and diatom analysis indicate that a relative marine transgression took place in Coll at c. 8000 14C years BP, an interpretation consistent with the results of pollen analysis of the organic material. The age and biostratigraphical interpretation of this relative marine transgression is in agreement with the results of sea-level research undertaken in recent years at Arisaig, western Scotland. However, the altitude at which the early-Holocene relative marine transgression is recorded in Coll is significantly lower than Arisaig, this difference reflecting the influence of differential glacio-isostatic uplift across the Inner Hebrides.
