Elsterian glacial period dating
For the following account, the modern coastline is taken as the boundary separating onshore and offshore Quaternary sedimentary deposits.
Compared with the fragmented onshore Quaternary sedimentary record, that offshore is considerably more complete, especially towards the shelf-edge where large submarine fans formed during major glacations (P915341).
The Elsterian was named for the Elster River of Germany.
Moraines are preserved at the shelf-edge north-west of mainland Scotland, more than 60 km west of the nearest coastline (Holmes et al., 1993; Stoker et al., 1993).
Conversely, marine deposits are preserved more than 10 km inland from the modern coastline at the head of the Moray Firth and at least 6 km inland near Elgin.
The Saalian glaciation is the best known glaciation as most of the surface expression of the northern half of the country has been shaped by it.
A continuous belt of deep glacial basins surrounded by large push moraines stretches across the country, and their intersections have led to a number of reconstructions for glacial events and dynamics.
