摘要:Abstract(#br)This study represents new petrophysical and paleomagnetic data obtained for the 1.64 Ga Suomenniemi diabase and quartz porphyry dyke swarm associated with Suomenniemi rapakivi granite. We also present petrophysical data for the coeval dykes of the Sipoo (1.63 Ga...

摘要:Abstract(#br)Baltica represents one of the key continents of the Mesoproterozoic supercontinent Nuna forming the core of it together with Laurentia and Siberia. This study presents new geochronological and paleomagnetic data obtained for the Häme diabase dyke swarm in southe...

摘要:Abstract(#br)We present a new Late Neoproterozoic paleomagnetic pole for Baltica from an inclined 272 m deep oriented sedimentary drill core in Hailuoto, Western Finland. The depositional age of the Hailuoto sediments is poorly constrained at 570–600 Ma. Three components of ...

摘要:Abstract(#br)We present here new palaeomagnetic, isotopic age and geochemical data from Archean and Early Palaeoproterozoic rocks in the eastern Fennoscandian Shield. We have studied NE–SW trending gabbronorite dyke sets and their host Archean basement rocks in the Vodlozero...

摘要:Abstract(#br)Results of a paleomagnetic study of Paleoproterozoic dykes and Archean host rocks in the eastern Fennoscandian shield are reported here. Most of the dykes are related to ca 2440 Ma layered intrusions and have isotopic ages between 2349 and 2476 Ma. The dykes for...

摘要:Abstract(#br)The Sipoo quartz porphyry dyke swarm (UPb zircon age 1.63 Ga) in southern Finland carries an intermediate to high coercivity remanent magnetization A N ( D = 22.2 °, I = −1.8 °, k = 34.2 , α95 = 13.3°, n = 5 dykes) which is regarded as primary. The Sipoo d...

摘要:Abstract(#br)Paleomagnetic results are presented for two Paleoproterozoic mafic dykes in the Taivalkoski area in northern Karelia Province of the Fennoscandian shield where, based on K-Ar data, the crust has seen minimal effects of the otherwise pervasive 1.8–1.9 Ga Svecofen...

摘要:Abstract(#br)The existence of the Paleoproterozoic supercontinent Nuna (Columbia, Hudsonland) has been proposed by several authors. Many recent reconstructions of this supercontinent are based on the assumption that Baltica and Laurentia form part of its core in a Northern E...

摘要:Abstract(#br)A paleomagnetic study of the Mesoproterozoic Satakunta sandstone formation, Western Finland is presented here. Two components of natural remanent magnetization (NRM) were isolated in the sandstone with alternating field (AF) and thermal demagnetization treatment...
