The Särv Nappe can be traced westwards from Jämtland into Trøndelag where it reappears as large scale lenses. The latter are dominated by tholeiitic dikes intruded into feldspathic sandstones. The intemal structure of these lenses is revealed in the orientation of the dikes, showing that the units have been rotated. The existence of these lenses provides new evidence of pinch-and-swell deformation of the nappe pile.
