Recent field work shows that the rocks of the Caledonian Trondheim basin cannot be followed into the Surnadal synform as previously indicated on the 1960 Geological Map of Norway (Holtedahl & Dons 1960). The structurally complicated Surnadal synform is separated from the Støren Group (Støren nappe) by a thrust zone. The rocks of the Surna Group have suffered two metamorphic events, an earlier medium-grade event superimposed by a low-grade event, white the Støren Group rocks have only been through the low-grade event.
