37 p, 3.4 MB 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 / Kara, J. (University of Turku. Department of Geography and Geology) ; Väisänen, M. (University of Turku. Department of Geography and Geology) ; Johansson, A. (Swedish Museum of Natural History. Department of Geosciences) ; Lahaye, Y. (Geological Survey of Finland) ; O'Brien, H. (Geological Survey of Finland) ; Eklund, O. (Abo Akademi University. Geology and Mineralogy)
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. 1. 88Ga) volcanic centres comprise bimodal plutonic batholiths surrounded by volcanic rocks of comparable ages and chemical compositions.

32 p, 1.3 MB Palaeoproterozoic adakite- and TTG-like magmatism in the Svecofennian orogen, SW Finland / Väisänen, M. (University of Turku. Department of Geography and Geology) ; Johansson, Å. (Swedish Museum of Natural History. Laboratory for Isotope Geology) ; Andersson, U. B. (Uppsala University. Department of Earth Sciences) ; Eklund, O. (Åbo Akademi University. Department of Geology and Mineralogy) ; Hölttä, P. (Geological Survey of Finland)
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. [...]
