Abstract
Reinvestigation of the tectonic and microstructural relations in the Dalslandian supracrustals and in the underlying granitic to granodioritic, mylo-gneiss basement provides evidence for a pre-Dalslandian deformation and recrystallization in the basement. This result is in agreement with earlier suggestions by van Overeem (1948; PhD thesis, Leiden University, Holland). It is demonstrated that the metamorphic and structural development in the basement is different from that in the Dalslandian supracrustals.
