Structural Geology and Tectonic Evolution of the Sognefjord Transect, Caledonian Orogen, Southern Norway—A Field Trip Guide / Структурная геология и тектоническая эволюция разреза Согнефьорд, Каледонский ороген, Южная Норвегия — Путеводитель

The fi eld trip described in this guide starts in the “Norwegian Alps,” the high mountain massif called Jotunheimen, and runs out along Sognefjorden, the world’s longest fjord, to the islands along the west coast of Norway. Geologically, the Sognefjord transect provides a complete cross section through the Caledonian orogenic belt, of Paleozoic age, which in Norway stretches along the west coast from Stavanger to North Cape, a distance of ~2000 km. This transect in southern Norway provides a superb and exceptionally well-documented example of late collisional tectonics in an Alpine-type orogen. It provides a continuous, 250-km-long cross section from the cratonic foreland, in the east, through the heavily deformed continental margin, to the remains of the Caledonian ocean complex, in the west. Detailed structural data are available along the whole transect, together with good stratigraphic, radiometric, petrological, and geophysical control. These data have been analyzed in terms of the kinematics and relative ages of the different deformation phases, and correlated along the whole transect. Logistically, the whole route is ideal for fi eld trips, both individually and in groups. It is easily accessible and well exposed, with good communications and different types of accommodations and services. The itinerary described in this guide is based on Excursion 28 of the 33rd International Geological Congress held at Oslo in August 2008. Many other itineraries are possible and practical, however, and it is hoped that this guide will also prove useful for planning trips on a do-ityourself basis <...>
