Asymmetrical folding in the Hawick Rocks of the Galloway area, Southern Uplands

Synopsis The asymmetry, scale and regionally uniform distribution of F1 folds in the Hawick Rocks do not support previous interpretations of the major structure. The F1–F4 phases of folding previously proposed are re-interpreted as two phases. The F2 folds are developed mainly along a 2–3 km wide strike belt. Variation in the scale and asymmetry of F1 folding across the Southern Uplands is outlined. The style of F1 folding in the Hawick Rocks is consistent with deformation accompanying sequential accretion of sediments at a subduction zone.
