Structural Geology and Tectonic Evolution of the Sognefjord Transect, Caledonian Orogen, Southern Norway—A Field Trip Guide

The Sognefjord transect through the Lower to Middle Paleozoic Caledonian orogenic belt in southern Norway provides a superb and exceptionally well-documented example of late collisional, Alpine-type tectonics. Logistically, the transect is ideal for field trips: It is easily accessible and well exposed; the scenery is breathtaking; and campsites, small pensions, and hotels are dotted along the route. Scientifically, it is one of the most spectacular orogenic cross sections in the world, exposing megastructures for hands-on study (e.g., Jotun nappe, with a demonstrable displacement of 200-300 km; Nordfjord-Sogn Shear Zone, with up to 50 km of normal displacement), as well as a collapsed, eclogitic orogenic root. This Field Guide is the first synthesis of the region to include detailed locality descriptions.
