Summary
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.
