Seismotomography of the East European platform: a three-dimensional P-velocity model of the mantle near Fennoscandia. Part II

open access: yesГеофизический журнал, 2010
This paper is an extension of a set of works on seismic tomography of East European platform. A velocity pattern given corresponds to the mantle under Fenno-Scandian shield as a northwestern part of EEP.

Geochemical and boron isotopic compositions of tourmalines from selected gold-mineralised and barren rocks in SW Finland [PDF]

open access: yesBulletin of the Geological Society of Finland, 2010
Tourmaline-bearing rocks and a number of gold occurrences coexist in southwestern Finland, in a region where extensive magmatism and hydrothermal systems occurred during the Svecofennian orogeny, 1.9-1.8 Ga ago.

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

open access: yesTransactions 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 ...

Evolution of migmatitic granulite complexes: Implications from Lapland Granulite Belt, Part I: Metamorphic geology [PDF]

open access: yesBulletin of the Geological Society of Finland, 2006
The Palaeoproterozoic Lapland granulite belt was juxtaposed between Archaean and Proterozoic terrains in the NE part of the Fennoscandian Shield concurrently with the accretion of Svecofennian arc complexes at ~1.9 Ga.

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

open access: yesTransactions 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.

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

open access: yesEstonian 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

open access: yesRussian 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.
