Sheet 96E Banff[edit]

Glacial and glaciofluvial features and the distribution of glacigenic deposits on Sheet 96E Banff. P915373.

The most notable sand and gravel resources of Sheet 96E (P915373) lie west of the valley of the River Deveron, between Banff and Boyndie (NJ 640 638). Glaciofluvial deposits assigned to the Blackhills Sand and Gravel Formation form the Hills of Boyndie, stretching south-westwards from Banff to Ladysbridge (NJ 651 636). Sand predominates, but gravel is more abundant towards the margins of the spreads. Clasts of quartzite, feldspathic red sandstone, granite and basic igneous rocks predominate within the gravel.

A significant resource of glaciofluvial sand and gravel is present on the western side of the valley of the River Deveron, but building developments in Banff have extended across the northern portion. Less attractive resources of water-saturated sand and gravel occur beneath the floodplain of the Deveron, underlying 2 to 3 m of alluvial silt. Farther east, in the vicinity of Paddocklaw Farm (NJ 662 617), Peacock et al. (1977) record sand and gravel containing clasts of metagreywacke, gneissose psammite, semipelite and slatey pelite. Notable resources may also be present within the glaciofluvial deposits flanking the Burn of Fishrie near its confluence with the River Deveron.
