Nature of a major tectonic discontinuity in the Svecofennian province of northern Sweden

Precambrian Research, 2001
Abstract The volcanic rocks of the Skellefte ore district (ca. 1.89–1.87 Ga), like other volcanic complexes of similar age in the Svecofennian orogenic province, have been regarded as juvenile arc material developed over a contemporaneous subduction zone, and subsequently accreted to the continent, during a period of very rapid crustal growth.

THE STRUCTURE OF LOW-VELOCITY ZONES IN THE MANTLE OF THE NORTHERN EUROPE

Transactions of the Karelian Research Centre of the Russian Academy of Sciences, 2015
The areas of low-velocity middle mantle shift into the transition zone are distinguished according to 3-d P-velocity model of the Fennoscandian shield mantle and its surroundings using Taylor approximation method.

Svecofennian crustal deformation of the Baltic Shield and U-Pb age of late-kinematic tonalitic intrusions in the Burtrask shear zone, northern Sweden

, 1995
Post-collisional crustal deformation of the Svecofennian region involved 1) lateral escape movements along crustal-scale dominantly dextral shear zones that roughly correspond to boundaries between volcanic and sedimentary terranes, and 2) crustal ...

Geochemistry, provenance, and tectonic setting of Paleoproterozoic metasedimentary and metavolcanic units of the Estonian Alutaguse region, eastern Fennoscandia [PDF]

Estonian Journal of Earth Sciences
This research focuses on the geochemical analysis of Paleoproterozoic metasedimentary and metavolcanic units in the Alutaguse region of northern Estonia, shedding light on the geodynamic evolution during the Svecofennian orogeny in eastern Fennoscandia ...

Petrophysical Properties of Rocks of the Northern Ladoga

Russian Journal of Earth Sciences
Northern Ladoga is a region of Southeastern Fennoscandia with complex geological and tectonic structure. It is crossed by the Raakhe–Ladoga junction zone of the Karelian craton and the Svecofennian orogen.

Biotite and muscovite 40Ar/39Ar geochronological constraints on the post-Svecofennian tectonothermal evolution, Forsmark site, central Sweden

, 2009
In order to characterize the post-Svecofennian tectonothermal evolution of the Fennoscandian Shield, 40Ar-39Ar biotite and some 40Ar-39Ar muscovite geochronological data are reported from a total of 30 surface outcrop and 1000 m long borehole samples at ...
