Glaciomarine model for upper Precambrian diamictites of the Port Askaig Formation, Scotland

The Dalradian sequences are different from modern and Pleistocene diamicts deposited by either lodgment or basal melt-out and fail to show evidence of tractional processes associated with basal ice movement. Scottish diamictite sequences are similar to assemblages of massive and stratified diamict lithofacies, of late Pleistocene age, deposited subaqueously below floating ice and recently described from the Lake Ontario basin.--Modified journal abstract.
