The accretion of ophiolitic terrains in the Scandinavian Caledonides

Abstract

The timing of ophiolite emplacement is discussed and it is demonstrated how the accretion of ophiolitic terrains is related to the Finnmarkian Orogeny. The continental miogeocline. of the Scandinavian Caledonides is shown to relate to the pre-Finnmarkian continental margin, and that it was effectively destroyed during the Finnmarkian Orogeny. The final assembly of the tectonostratigraphy of the Scandinavian Caledonides, is however the result of superimposed orogenic cycles. The pattern of development bears many resemblances to that of the Appalachian orogen in North America.
