Conjugate folds consisting of a system of paired monoclinal flexural folds have been observed in association with shear joints and lamproschists in rocks of the Moine nappe in the Ben Klibreck area, central Sutherland, Scotland. They occur some 15 miles east of the Moine thrust zone. Spatial relationships and structural evidence indicate that formation of the joints and flexures was closely related in time and took place after emplacement of the Newer Granites and before Old Red Sandstone sedimentation. Correlation with events in the thrust zone shows that thrust movements occurred in lower Old Red Sandstone time and were contemporaneous with rapid isostatic uplift of the axial zone of the Caledonian orogen.
