چکیده انگلیسی
This paper investigates the geometry, deformation history and age of the synkinematic granitic Årdal dyke complex in the Upper Jotun Nappe, SW Norway. The typically subparallel north-trending dykes are folded and boudinaged, reflecting emplacement and deformation in a top-to-southeast non-coaxial strain field. The synmagmatic strain field is interpreted to reflect thrusting of the nappe at 427 ± 1 Ma, the zircon U–Pb TIMS age of the Årdal dyke complex. The Upper Jotun Nappe is a displaced part of the Baltic Shield; the age is therefore a minimum age for initiation of Caledonian thrusting of crystalline Baltica crust in western Norway.
