Tectonometamorphic development of Devonian rocks of western Solund, and regional implications.

Many modern accounts of Devonian rocks of western Norway, which emphasise the extensional phenomena affecting them, tend to ignore or gloss over the deformation and metamorphism which these rocks have suffered during contractional deformation. The present account describes extensive ductile folding, penetrative cleavage formation and low-grade metamorphism developed in the Devonian rocks of the Scandinavian Caledonides share a common tectonothermal development. In summary, the bulk observations support a regional contractional event which, conceptually, may relate either to a Mid-late Devonian arc-continent collision, or to a transpressional strain regime.
