The gneisses below the Cambrian schist or Eocambrian flagstones in the central Norwegian Caledonides have been considered of Precambrian age, but the fact that the contact is always concordant has been explained as due to Caledonian tectonization. The author describes shortly a number of localities of this contact and concludes that a more likely explanation is that the rocks are really close to concordant, e.g. the Precambrian rocks within the Trondheim region were essentially flat-lying at the begin of Cambrian time.
