Footprint of the Baltic Ice Stream: geomorphic evidence for shifting ice stream pathways

Boreas, Volume 53, Issue 1, Page 4-26, January 2024.
The Baltic Ice Stream, a large fast‐flowing sector of the last Fennoscandian Ice Sheet that occupied the present‐day Baltic Sea basin, was first conceptualized in the earliest days of glacial geological research in Scandinavia. Landform and sedimentological evidence from the terrestrial margins support the concept and numerical ice‐sheet models ...

Geometry and kinematic evolution of ductile shear zones in the Ersfjord Granite (1.79 Ga), West Troms Basement Complex: A Svecofennian accretionary thrust system [PDF]

, 2018
The Ersfjord Granite is a 1.79 Ga felsic intrusion in the geological region of West Troms Basement Complex (WTBC). Its intrusion history and evolution relative to surrounding Neoarchean TTG-gneisses has until now been poorly understood, providing the ...

STRESS-METAMORPHISM AND STRESS-METAMORPHITES IN PRECAMBRIAN OF THE LADOGA REGION

Transactions of the Karelian Research Centre of the Russian Academy of Sciences, 2015
The tectonites confined to fault zones with abnormally high, up to 12 kbar, pressures, which appear to be the products of stress-metamorphism of relatively late stage of deformation-metamorphic evolution, are identified in the regionally metamorphosed ...

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 ...

The Vaasa Migmatitic Complex (Svecofennian Orogen, Finland) : Buildup of a LP-HT Dome During Nuna Assembly [PDF]

, 2020
Tectonic evolution of the Paleoproterozoic Vaasa migmatitic complex (VMC) in the central part of the Svecofennian accretionary orogen is deciphered using aeromagnetic and gravity maps, deep seismic and magnetotelluric profiles, and structural and ...

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.

Penetrative ductile deformation and amphibolite-facies metamorphism prior to 1851 Ma in the western part of the Svecofennian orogen, Fennoscandian Shield

, 2007
The Svecofennian orogen in the Fennosandian Shield consists of several Palaeoproterozoic meta-igneous provinces that generally young progressively southwards and westwards.

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.
