Summary

The Durn Hill Quartzite of Redhythe Point, near Portsoy, can be divided into an eastern shear zone and a western foliated zone. The latter region is typical of most quartzites between the coast and Keith. NW-SE trending flexures, pure shear folding and wrench faults, interfere with the dominantly NE-SW trending folds of the steep limb of the Boyndie Syncline. Possible large scale NW-SE trending monoclines were identified at Redhaven, Aberchirder and Rothes. Such structures bring down the older fold axial traces and isograds towards the NE.
