Sr–Nd isotope and geochemical characterisation of the Paleoproterozoic Västervik formation (Baltic Shield, SE-Sweden): a southerly exposure of Svecofennian metasiliciclastic sediments

, 2011
The Paleoproterozoic Vastervik formation represents the southernmost exposure of Svecofennian metasediments and comprises a large psammitic succession of up to 5,000 m thickness dominated by quartzite with minor pelite and arkose. The Vastervik formation

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 ...

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 ...

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.

Lateral spreading in the Svecofennian mid-crust revealed by seismic attribute analysis

, 2014
In orogenic belts, crustal thickening precedes rheological weakening of the middle and lower orogenic crust leading to lateral spreading and, ultimately, to collapse of an orogen. Recent studies have implied similar development in the middle crust during

A seismic study of the mid- and lower-crust beneath the sea of Bothnia: BABEL line 1 [PDF]

, 1994
In the Autumn of 1989, Durham University took part in the BABEL Project, a collaboration of scientists from five nations recording wide angle and normal incidence seismic data in the Baltic Shield.
