Geological magazine : Vol. 87 Iss. 1-6 Year. 1950Summary: Abstract
The principal tectonic terms employed are defined. A specimen of sheared quartzite from Corshellach is described. Shear-planes, drag-folds, and lineation are syngenetic. Their geometric relations show that the lineation is in b. Also described is a specimen of folded marble and graphite schist from Urlarmore. Elongated bodies of graphite schist represent tectonic thickening along the antiform hinges. Their maximum dimension, which is much greater than any other, is parallel to the lineation, but they have not suffered extension in this direction. The form of folds and rotated bodies shows that the lineation is again in b. The sense of the movement was towards the south-west. It is believed that throughout mid-Strathspey and Strathavon similar lineations bear the same relations to the kinematic directions.
