Extract

CAPPING many of the hill-tops of the Buchan district of Aberdeenshire there are extensive spreads of gravel containing pebbles of white quartzite and of flint. Their north-western limit is on the Delgaty estate, near Turrifi, where, at an elevation of 350–400 feet, there is a small patch of quartzite gravel a mile and a half to the north-east of the town. Nearly eight miles to the south, on Windyhills, two miles north-east of Fyvie, a more extensive outlier occurs. These two patches are shown in Fig. 1. The Windyhills spread is nearly a square mile in area, and it occupies the summit of a low flat-topped ridgo at an elevation of 370–400 feet. Like the Delgaty gravels, it is evidently the remains of a deposit formerly much more extensive and reduced greatly in area by denudation. It consists mainly of white quartzite pebbles, flint pebbles, and white clayey sand, and its resemblance to the Delgaty gravels is so close that no doubt has been entertained that they belong to the same period and formation.
