Svecofennian volcanism in northernmost Sweden

open access: yes, 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 and submarine back-arc environments, whereas epithermal gold deposits are being formed in volcanic ...

1.90-1.88Ga arc magmatism of central Fennoscandia: geochemistry, U-Pb geochronology, Sm-Nd and Lu-Hf isotope systematics of plutonic-volcanic rocks from southern Finland

open access: yesGeologica Acta, 2016
The earliest Svecofennian magmatism in southern Finland has been dated at 1.90-1.88Ga. As an example of this, the Orijärvi (ca. 1.89Ga) and Enklinge (ca.

Palaeoproterozoic adakite- and TTG-like magmatism in the Svecofennian orogen, SW Finland

open access: yesGeologica Acta, 2013
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.

T-t Evolution of the Early Proterozoic Rocks in the Northern Ladoga Region from the Data on U-Pb, Rb-Sr and Sm-Nd Systems in Minerals

open access: yesГеодинамика и тектонофизика
This paper presents the results of a study of isotopic systems in minerals and rocks in southern margin of the epi-Archean Karelian craton in the zone of its junction with the Svecofennian mobile belt.
