The Kunes Nappe is a basement unit (Storfjord Basement Complex) which is separated here from the Laksefjord Nappe in central Finnmark.It has
features that are typical of basement rocks coring tectonic windows in the Scandinavian Caledonides (here called 'Window Basement' ). These are:
A thin unconformable cover succession (Adamsfjord Formation); abundant imbrication; early SE-directed deformation overprinted by E- to ESE-vergent folding; a metamorphic grade that is slightly higher than in the underlying Lower Allochthon (lower greenschist facies v. u. anchizone); a
domal form; a restored position immediately internal to the Lower Allochthon. In addition, the Kunes Nappe has its basal thrust exposed, providingfield evidence to support the hypothesis that the Window Basement is allochthonous throughout the orogen.
