The geology of the Vaddas area, Troms: a key to our understanding of the Upper Allochthon in the Caldonides of northern Norway
The Vaddas area in the North Norwegian Caledonides is underlain by the Corrovarri Nappe, the uppermost unit of the Kalak Nappe Complex, and the overlying Vaddas Nappe representing the lowermost unit of the Reisa Nappe Complex. Both nappes form part of the Upper Allochthon. Only the upper part of the...
