Svecofennian intra-orogenic gabbroic magmatism: A case study from Turku, southwestern Finland [PDF]
Bulletin of the Geological Society of Finland, 2014 Using single-grain zircon U-Pb dating by LA-MC-ICPMS and whole-rock geochemistry, we have studied the Palaeoproterozoic gabbroic rocks from Moisio in southwest Finland. Three ages were obtained.

U-Th-Pb zircon geochronology on igneous rocks in the Toija and Salittu Formations, Orijärvi area, southwestern Finland: Constraints on the age of volcanism and metamorphism [PDF]
Bulletin of the Geological Society of Finland, 2008 Zircons from a felsic volcanic rock in the Toija Formation and a synvolcanic gabbro intrusion in the Salittu Formation within the Orijärvi area were dated by U-Th-Pb SIMS in order to provide depositional constraints on these formations.

An ion microprobe U-Th-Pb study of zircon xenocrysts from the Lahtojoki kimberlite pipe, eastern Finland [PDF]
Bulletin of the Geological Society of Finland, 2001 Eleven relatively large (diameter 1–2 mm) zircon grains extracted from the Lahtojoki kimberlite pipe (Eastern Finland Kimberlite Province) have been analysed by the ion microprobe NORDSIM for their U- and Pb- isotopic composition.

Timing of Palaeoproterozoic crustal shearing in the central Fennoscandian Shield according to U-Pb data from associated granitoids, Finland [PDF]
Bulletin of the Geological Society of Finland, 2001 Granitoids in the Finnish part of the Fennoscandian Shield were created by numerous Archaean and Palaeoproterozoic tectonic events. Late phases of Palaeoproterozoic, Svecokarelian deformation created ductile, crustal-scale shear zones, of which the N-S ...

Reconstruction of the Dead (Grey) Dune evolution along the Curonian Spit, Southeastern Baltic [PDF]
Bulletin of the Geological Society of Finland, 2013 One of the unique places in Europe in both environmental and cultural terms is the Curonian Spit – a massive sandy barrier separating the Curonian Lagoon from the Baltic Sea. Straddling both the Lithuanian and the Russian parts, the spit is included into

Relationships between sanukitoids and crust-derived melts and their implications for the diversity of Neoarchaean granitoids: A case study from Surmansuo and nearby areas, Eastern Finland [PDF]
Bulletin of the Geological Society of Finland, 2014 We present new isotopic data (U-Pb and Sm-Nd) from the Neoarchean granitoids of the Lentua complex, which is a part of the Western Karelia subprovince of the Fennoscandian Shield.

Rb-Sr whole-rock isotopic study of late Archaean and early Proterozoic granitoid intrusions, Kainuu, Eastern Finland [PDF]
Bulletin of the Geological Society of Finland, 1988 A tonalite-granodiorite-granite suite emplaced during the late Archaean D3 deformational phase yields a six point isochron age of 2,500 ± 270 Ma and an initial 87Sr/86Sr of 0.7044 ±0.0018.

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 ...
