3. Neotectonics
From
studies of the buried beaches and the later shorelines which overlie them, the
morphological and stratigraphical approach was employed by Sissons in the Forth
valley to identify evidence that the uplift of the land involved a degree of
dislocation, at least partly along pre-existing fault lines. These “neotectonic”
effects had not been so conclusively demonstrated before, and indeed the Forth
valley study details some of the clearest evidence for neotectonic effects in
shorelines in any formerly glaciated area. Importantly, Sissons (1972) was able
to show that glacio-isostatically uplifted areas of the crust may actually
comprise small segments separated by faults. This observation remains one of the
unsung discoveries of aspects of land uplift in Scotland.
