Di. Benn et Dja. Evans, GLACIOMARINE DELTAIC DEPOSITION AND ICE-MARGINAL TECTONICS - THE LOCHDON SAND MORAINE, ISLE OF MULL, SCOTLAND, JQS. Journal of quaternary science, 8(4), 1993, pp. 279-291
Detailed descriptions are given of sediments exposed in the 'Loch Don
Sand Moraine', Isle of Mull, Scotland. Two distinct sediment-landform
associations occur within the 'moraine': (i) a Gilbert-type glaciomari
ne delta complex graded to ca. 34 m Ordnance Datum; and (ii) thrust mo
raines consisting of deformed sands and silts. Whereas previous studie
s have attributed the 'moraine' to a single glacial readvance, this pa
per shows that the delta and the thrust moraines formed during ice-she
et deglaciation and the Loch Lomond Readvance, respectively. Depositio
nal conditions and the palaeoenvironment for each stage of 'moraine' f
ormation are reconstructed. During the Loch Lomond Readvance, till dep
osition and thrust moraine formation appear to have been controlled by
drainage conditions in the marginal zone of the glacier.
