    Lu–Hf Isotope-Geochemical Zircon Systematics and Genesis of the Neoarchean Alkaline Granites in the Keivy Megablock, Kola Peninsula

    Abstract—Alkaline and subalkaline granites of the Keivy megablock belong to the potassic alkali-calcic ferroan rocks enriched in large-ion lithophile, high-field strength and rare-earth elements. Based on these c...

    Sites and Origin of Noble Gases in Minerals: A Case Study of Amphibole from Alkaline Granitoids of the Kola Peninsula

    The paper presents newly acquired data on the budget and mobility of isotopes of noble gases in samples of amphibole, a mineral commonly characterized by relatively high He concentrations compared to other roc...

    Trace element composition and Lu-Hf isotope systematics of zircon from plagiogneisses of the Kola superdeep well: Contribution of a Paleoarchean crust in Mesoarchean metavolcanic rocks

    Zircons have been studied in three samples of Archean plagiogneisses from the Kola superdeep well (SG-3). The crystals consist of cores, magmatic shells, and metamorphic rims. The cores and shells are characte...

    Duration of the formation and sources of the granitoids of the Litsk-Araguba Complex, Kola Peninsula

    Postorogenic granitoids of the Litsk-Araguba Complex compose a chain of intrusive bodies around 850 km2 in area, which are confined to the NE-trending deep-seated fault zone. Results of U-Pb zircon dating indicat...

    Geology and geochronology of neoarchean anorogenic magmatism of the Keivy structure, Kola Peninsula

    Anorogenic magmatic complexes were formed during protoplatformal evolution of the Keivy structure. This evolution ended with development of aluminous schists, which were derived by deep disintegration and rede...

    Sm-Nd systematics and petrology of postorogenic granitoids in the northern Baltic Shield

    In the northern part of the Baltic Shield, quartz diorites, diorites, and monzodiorites compose massifs of postorogenic granites, in which younger granite phases are restricted to their central parts, and dike...

    Helium and argon isotopes in lower crustal xenoliths from the belomorian mobile belt

    The isotopic systematics of noble gases (He and Ar) were studied in Neoarchean and Paleoproterozoic lower crustal xenoliths from the Belomorian mobile belt. The xenolith suite is dominated by garnet granulites (G...

    Composition and structure of the lower crust of the Belomorian Mobile Belt, Baltic Shield

    The lower crust of the Belomorian Mobile Belt consists predominantly of garnet peridotites with subordinate amounts of pyroxenites and spinel peridotites, which occur as xenoliths in Devonian diatremes and dik...
