The complexity of folding in the Scottish Highlands has recently been emphasized by several workers. One area that shows this very well is the hill of Ord Ban, near Aviemore. Quartzite in superposed recumbent folds with a north-south trend is separated by a slide from schist and marble with east-west folds. The two foldings are described, contrasted, and interpreted. Evidence of an early deformation, with mylonization, is shown in the quartzite; the monoclinal folds in the marble, with twinning of calcite and dolomite, are younger.
