摘要:The Salittu Formation is one of the few metavolcanic successions in the U-Pb zircon single grain dating using the LA-MC-ICP-MS technique was utilized to determine the age of the host rocks of the Juomasuo Au-Co-Cu deposit located in the late Archean Kuusamo supracrustal belt. Eve...

摘要:The Vaasa batholith, western Finland, is a large, peraluminous granitoid pluton that crystallized at 1.88–1.87 Ga during the culmination of the Svecofennian orogeny. The batholith has gradual contacts, through metatexites and diatexites, with the enveloping metasedimentary r...

摘要:Abstract(#br)Peralkaline to marginally metaluminous alkali-feldspar syenites and quartz alkali-feldspar syenites are hosted by subalkaline, ferroan rapakivi granites in the 1644 Ma Suomenniemi complex of southeastern Finland. These alkali syenites form NW-oriented dikes and ...

摘要:Abstract(#br)Mesozoic Karoo-related lavas and dikes from north Vestfjella, Dronning Maud Land, comprise four magma types (CT1, CT2, CT3, and CT4) that occur intimately interspersed in a 300-m-thick lava succession and associated dike swarm. The CT1 lavas and dikes exhibit lo...

摘要:Abstract(#br)Late Neoproterozoic (Ediacaran) evolution of the northernmost segment of the Arabian-Nubian Shield (ANS) included vast intrusion of granitoids and development of volcano-sedimentary basins. Here we describe two of such volcano-sedimentary successions (Rutig and ...

摘要:Abstract(#br)The evolution of the Svecofennian Orogen spans from 1.95 Ga to 1.80 Ga with the main crust-forming activity having taken place 1.90–1.87 Ga ago. Subsequent deformation was largely concentrated to southern Finland where transpressional structures indicate lithosp...

摘要:Abstract(#br)The ca. 1525 Ma igneous Mucajaí anorthosite–monzonite–granite (AMG) complex in northern Brazil is a rare manifestation of Mesoproterozoic intraplate magmatism in the northern Amazonian Craton. The complex comprises a two-phase rapakivi granite batholith wit...

摘要:Abstract(#br)Early Paleoproterozoic extension in the Archean craton of the Fennoscandian shield led to the emplacement of several 2.44 Ga layered gabbroic intrusive complexes in northern Finland and adjacent Russia. Closely associated with them are felsic rocks of similar ag...
