Development of an in-situ magmatic dome (Svecofennian accretionnary orogen, Finland) [PDF]
, 2014 This study focuses on the formation of the 100 km wide Vaasa magmatic dome (Svecofennian orogen, Finland). It is cored by diatexite migmatites and granitoids and gradually mantled by metatexite migmatites and mica schist.

Palaeoproterozoic adakite- and TTG-like magmatism in the Svecofennian orogen, SW Finland
Geologica Acta, 2013 The Palaeoproterozoic Svecofennian orogen in the Fennoscandian shield is an arc accretionary orogen that was formed at c. 1.92-1.86Ga. Arc accretion, magmatism and the subsequent continent-continent collision thickened the crust up to c.

Svecofennian volcanism in northernmost Sweden [Elektronisk resurs]
, 1995 Volcanism and volcanic processes are important factors for ore formation. The environment of the volcanism plays an important role for which type of ore that will be formed. For instance, massive sulphide deposits are now being formed in mid-ocean ridges

Chronology and geochemistry of late Svecofennian processes in northern Sweden
Gff, 1989 Radiometric and geochemical data have been used to characterize the concluding stages of the Svecofennian orogeny in northern Sweden. U-Pb zircon ages of 1879 +- 7 and 1858 +- 9 Ma have been obtained from two unfoliated granitoids of the North ...
