Sm-Nd data for mafic-ultramafic intrusions in the Svecofennian (1.88 Ga) Kotalahti Nickel Belt, Finland - Implications for crustal contamination at the Archaean/Proterozoic boundary [PDF]
Bulletin of the Geological Society of Finland, 2007 Sm-Nd data were determined for eight mafic-ultramafic intrusions from the Svecofennian (1.88 Ga) Kotalahti Nickel Belt, Finland. The intrusions represent both mineralized and barren types and are located at varying distances from the Archaean/Proterozoic

Palaeoproterozoic adakite-and TTG-like magmatism in the Svecofennian orogen, SW Finland [PDF]
Geologica Acta, 2022 The Palaeoproterozoic Svecofennian orogen in the Fennoscandian shield is an arc accretionary orogen that was formed at c. 1.92-1.86Ga. Arc accretion, magmatism and the subsequent continent-continent collision thickened the crust up to c. 70km, forming

Svecofennian volcanism in northernmost Sweden
, 1995 Volcanism and volcanic processes are important factors for ore formation. The environment of the volcanism plays an important role for which type of ore that will be formed. For instance, massive sulphide deposits are now being formed in mid-ocean ridges

Structural features and emplacement of the late Svecofennian Perniö granite sheet in southern Finland [PDF]
Bulletin of the Geological Society of Finland, 1996 The 1840-1830 Ma old Perniö granite occupies the southern margin of the Sauvo-Perniö granite area located in the western part of the late Svecofennian granite-migmatite zone in southern Finland.

Crustal development in relation to granitic magmatism in regard to D/H partition between coexisting hornblende and biotite in the Svecofennian belt [PDF]
Bulletin of the Geological Society of Finland, 1993 Tie-lines in the σD-XFe diagram of hornblende and biotite in Japanese island arc granites give commonly a similar slope to that derived from the equation of Suzuoki-Epstein's experimental work (1976).
