The Precambrian geology of the south-eastern part of map sheet Skoganvarre 2034 IV.

ABSTRACT The geology and structural history of the western margin of the Karasjok Belt in the Skoganvarre district are described. Archean supracrustals of the Karasjok group are thrust westwards across the Archean Basal gneiss complex and its ?Early Proterozoic metasedimentary cover. The Stallucak'ka Thrust Zone is a major tectonic dislocation containing mylonites derived from a wide variety of protoliths. A discription of the main lithologies present within the thrust zone and its wall-rocks is followed by an account of the structural and metamorphic evicence for westward translation of the Karasjok group. Some consideration is given to the likely age, causes and regional implications of this thrusting, and to the regional correlation of the various tectonostratigraphic units.
