Timing of Svecofennian crustal growth and collisional tectonics in Åland, SW Finland [PDF]
Bulletin of the Geological Society of Finland, 2004 In an effort to quantify the time parameter in the tectonomagmatic evolution of what has been called the Southern Svecofennian Arc Complex (SSAC) of SW Finland, advanced radiometric dating techniques have here been applied to rock groups of key ...

The Pyhäntaka formation, Southern Finland: A sequence of metasandstones and metavolcanic rocks upon an intra-orogenic unconformity [PDF]
Bulletin of the Geological Society of Finland, 2011 Detrital zircon studies suggest that the few quartzite occurrences in southern Finland are younger than 1.87 Ga and express sedimentation after 1.89–1.87 Ga accretional deformation and metamorphism in the Svecofennian orogenic belt.

Pre-1.91 Ga deformation and metamorphism in the Palaeoproterozoic Vammala Migmatite Belt, southern Finland, and implications for Svecofennian tectonics [PDF]
Bulletin of the Geological Society of Finland, 2004 A metamorphic event in the Vammala Migmatite Belt (VMB) at ~1.92 Ga, revealed by SHRIMP U-Pb analyses of both zircon overgrowths and monazite, is interpreted as post-depositional and is correlated with the development of the early high-grade schistosity.

New monazite U-Pb age constraints on the evolution of the Paleoproterozoic Vaasa granitoid batholith, western Finland [PDF]
Bulletin of the Geological Society of Finland, 2016 The Vaasa batholith, western Finland, is a large, peraluminous granitoid pluton that crystallized at 1.88–1.87 Ga during the culmination of the Svecofennian orogeny.

U-Pb zircon determinations from the Keikyä Breccia and other sites in the Svecofennides: indications of a Svecokarelian protocrust [PDF]
Bulletin of the Geological Society of Finland, 1996 Heterogeneous zircon populations from four different localities within the Svecofennian area in Finland demonstrate that the ca. 1890 Ma old syntectonic granitoids contain older material, probably belonging to the ca. 1950 Ma Svecofennian protocrust, the
