Intertidal peat deposits and early Holocene relative sea-level changes, Traigh Eileraig, Isle of Coll, Scottish Hebrides

An intertidal organic deposit is described for Traigh Eileraig, Isle of Cel l, Scottish Inner Hebrides. The organic sediments are overlain by sands con taining marine diatoms. Radiocarbon dating and diatom analysis indicate tha t a relative marine transgression took place in Coil at c. 8000 C-14 years sp, an interpretation consistent with the results of pollen analysis of the organic material. The age and biostratigraphical interpretation of this re lative marine transgression is in agreement with the results of sea-level r esearch undertaken in recent years at Arisaig, western Scotland. However, t he altitude at which the early-Holocene relative marine transgression is re corded in Coil is significantly lower than Arisaig, this difference reflect ing the influence of differential glacio-isostatic uplift across the Inner Hebrides.
