The stratigraphy and structure of the Moine rocks N of the Schiehallion Complex, Scotland

Sedimentary structures are used to establish a 'Younger' Moine stratigraphical succession in Strathtummel. Polyphase re-folding of the Moine sequence between Schiehallion and Drumochter can be clearly subdivided into primary and secondary deformations. Primary NE-SW trending deformational events D1 and D2 include the formation of the south-eastward facing D1 Atholl nappe re-folded by strongly overturned D2 folds which become upright on the crest of the Drumochter dome. Secondary deformation resulted in D3 (oblique) and D4 (transverse) major folds, both of which plunge into the SE quadrant.
