Popis: | Marine, fluvial and fluvioglacial terraces, and other landforms and deposits associated with them, have been mapped over an area that extends from Dundee to Stonehaven along the coast, and inland in places as far as the Highland edge. All well-defined terraces have been levelled at approximately 50 mintervals along their length. Analysis of the altitude data permits the recognition of eight glacio-isostatically tilted raised shorelines of Late Devensian age, sloping down towards E5dS, the lowest at 0.2 m/km and the others at gradients of 0.50-0.85 m/km. Successively lower and less steeply inclined shorelines were formed in close association with a westward-receding ice margin, and there are indications that crustal response to unloading may have been immediate and rapid. Five of the shorelines are correlated with five of the six Late Devensian shorelines recognized by the authors (1966) in eastern Fife, allowing contemporaneous positions of the wasting ice-sheet margin in the two areas to be postulated. |
