Based on our new U–Pb isotope data (SHRIMP-II) for the Voronezh Crystalline Massif (VCM) and on published U–Pb data for the Archean rocks of the Ukrainian Shield (USh), we have substantiated the main stages of the Archean evolution of the Sarmati

Isotopic timing of the magmatic and metamorphic events at the turn of the Archean and Proterozoic within the Belomorian belt, Fenno-Scandinavian shield

It is proved that dating high-grade metamorphism events through dating of migmatites is quite efficient. Our investigation has made it possible to identify two events of 2500 and 2700 Ma and to estimate the age of an igneous protolith for both tonali

This report presents data on the geological structure and location of the orthopyroxenite inclusion in gneissic enderbites of the Bug granulite–gneiss domain. Three stages of orthopyroxenite formation were identified on the basis of studies of the

We present new data on geochemistry, isotopic geochemistry, and geochronology of the Early Cambrian igneous rocks of the northeastern Siberian Craton (Kharaulakh anticlinorium, contact between the Siberian Platform and the West Verkhoyansk sector of

Zircon from charnockite gneiss, charnockite, and leucosome of migmatite in the Nimnyr Block of the Aldan Shield

Autor: L. M. Samorukova, N. G. Berezhnaya, I. S. Sedova, Sergey G. Skublov, V. A. Glebovitsky

Publikováno v: Geology of Ore Deposits. 57:552-569

The microgeochemistry of zircon was studied in three samples: charnockite gneiss (1594), charnockite (1594a), and migmatite leucosome Lc4 (1594c). Prismatic (Zrn I) and oval (Zrn II) zircon morphotypes are distinguished in the first two samples. Most

New data on the U-Pb (SHRIMP II) age of zircons from aluminous gneisses of the Archean Kola Group of the Baltic shield and the problem of their interpretation

Autor: N. G. Berezhnaya, P. A. L’vov, R. I. Mil’kevich, T. A. Myskova, V. A. Glebovitskii

Publikováno v: Doklady Earth Sciences. 463:738-745

New data on the U-Pb (SHRIMP II) age are obtained for aluminous gneisses of the Kola Group of the Baltic shield. Gneisses are typically ascribed to metasedimentary rocks with detrital zircons. Our work interprets the isotopic data based on the magmat
