ABSTRACT The Solund­Hyllestad­Lavik area affords an excellent opportunity to understand the ultrahigh-pressure
Scandian orogeny because it contains a near-complete record of ophiolite emplacement, high-pressure
metamorphism and large-scale extension. In this area, the Upper Allochthon was intruded by the
c. 434 Ma Sogneskollen granodiorite and thrust eastward over the Middle / Lower Allochthon, probably
in the Wenlockian. The Middle / Lower Allochthon was subducted to c. 50 km depth and the
