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

Complexities and span of crystallization ages of a non-foliated Svecofennian granite pluton
GFFUpper-intercept U-Pb ages (TIMS) of two non-foliated I-type granites are 1887 ± 20 Ma (part of a granodiorite-granite sequence) and 1881 ± 2 Ma (leucogranite with transitions into pegmatite).

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 ...

Late-orogenic Svecofennian deformation in SW Finland constrained by pegmatite emplacement ages
, 1996 Late stages of the Svecofennian orogeny in SW Finland were related to a tranpressional stress field and dextral movements along crustal scale shear zones under decreasing temperature and pressure conditions.

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

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.
