Ar-40/Ar-39 hornblende geochronology from the Forsmark area in central Sweden : constraints on late Svecofennian cooling, ductile deformation and exhumation
At Forsmark, ca. 120 km north of Stockholm in central Sweden, ductile high-strain belts with WNW to NW trend anastomose around tectonic lenses with an inferred lower degree of ductile strain. Previous studies of ductile deformation zones with WNW to NW trend, elsewhere in the western part of the Svecofennian orogen in central Sweden, have yielded estimates for the timing of at least one phase of d
