New Light on Sedimentation and Tectonics

Abstract

1. The Loch Awe Nappe succession was correctly stated in 1922.2. The Iltay Nappe succession was correctly stated in 1922.3. The Ballappel Foundation succession was wrongly stated in 1922.4. The recumbent-fold structure of the Ballachulish district is due to rotation of middle limbs by drag from above or from below.5. Graded bedding is as important as current bedding in marking a facies group among sandstones. It often indicates accumulation in rather deep water, to which sandy material has penetrated, perhaps as a result of seaquakes.
