Is the Estonian Alutaguse Section of Eastern Fennoscandia a continuation of the Southern Svecofennian Finnish Terranes, or is it akin to the Swedish Bergslagen region?

open access: yes
<p>This research explores the geochemistry of Paleoproterozoic metasedimentary and metavolcanic units in the Alutaguse region of North Estonia and the South Svecofennian (SS) zones, including Ladoga, Saimaa, Häme Belt, and Uusimaa Belt, to better ...

Svecofennian volcanism in northernmost Sweden [Elektronisk resurs]

open access: yes, 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

Geological Evolution of the Supracrustal Palaeoproterozoic Hamrånge Group: A Svecofennian Case Study

open access: yes, 2010
The work presented in this thesis utilizes several geological methods to investigate the origin and evolution of the supracrustal rocks in the Palaeoproterozoic Hamrånge Group (HG) in the south-central Swedish Svecofennian. The first paper is based on whole-rock geochemistry to show the plate tectonic setting of volcanic rocks within the HG.

Analog models of the lateral spreading of a thick three-layer crust : implications for the Svecofennian orogen in Finland [PDF]

open access: yes, 2016
Our knowledge of the crustal structure of the Precambrian Svecofennian orogen has been enhanced during the last decade. Much of the new knowledge is due to the deep seismic reflection studies (Finnish Reflection Experiments; FIRE), which transect the ...
