Lateglacial and postglacial shorelines in western Scotland

Some recent studies of raised shorelines in western Scotland, which are gaining international acceptance, are assessed in the light of subsequent criticisms. Fieldwork has revealed that there are differences in altitude measurements, interpretations, and conclusions between these studies and the present one in Lorn and eastern Mull. Two short lateglacial shorelines are tentatively suggested, but there is a general abesence of clear, widespread shorelines of this age. The Main Postglacial Shoreline has a gradient of 0.05 m/km, considerably less than found in previous studies in both western and south‐cast Scotland. Subsequently, as relative sea level fell to its present level, two fairly clear shorelines with low gradients were formed together with traces of intermediate ones. The influences of the. Falls of Lora rock bar and of exposure on showline altitude are also examined.
