AGE LIMITS OF HIGH-GRADE METAMORPHIC SUPRACRUSTAL COMPLEXES IN THE CENTRAL ALDAN SHIELD: SM-ND ISOTOPIC DATA

Kovach V.P.; Kotov A.B.; Sal'nikova E.B.; Velikoslavinskii S.D.; Zagornaya N.Yu.; Berezkin V.I.; Smelov A.P. (1999)

First investigation results on Sm-Nd isotope systems in clastic metasedimentary and metavolcanic rocks from the high-grade metamorphic supracrustal complexes of central Aldan Shield are used to approximately evaluate their ...
AGE LIMITS OF THE GREENSTONE BELTS OF THE WESTERN ALDAN SHIELD

Kotov A.B.; Anisimova I.V.; Glebovitsky V.A.; Kovach V.P.; Sal'nikova E.B.; Zagornaya N.Yu.; Smelov A.P.; Berezkin V.I. (2004)

The main features in the geological structure of the western Aldan Shield are largely determined by nearly meridional and NE-trending fault zones that host numerous tectonic fragments composed of weakly metamorphosed ...
CRUST-FORMING PROCESSES IN THE GEOLOGIC DEVELOPMENT OF THE TUVA-MONGOLIA MASSIF: SM-ND ISOTOPIC AND GEOCHEMICAL DATA FOR GRANITOIDS

Kozakov I.K.; Kovach V.P.; Kotov A.B.; Salnikova E.B.; Zagornaya N.Yu.; Yarmolyuk V.V. (2003)

The compositions of igneous rocks from the Tuva-Mongolia massif were studied. These rocks were formed during the precollisional, syncollisional, and postcollisional stages of massif formation. The compositions of strongly ...
SM-ND ISOTOPIC SYSTEMATICS OF THE KURUMKAN SUBGROUP, THE IENGRA GROUP OF ALDAN SHIELD

Kovach V.P.; Kotov A.B.; Salnikova E.B.; Zagornaya N.Yu.; Berezkin V.I.; Smelov A.P. (1996)

The first data on the Nd isotopic composition in high-AI gneisses and associated gamet-hypersthene-biotite plagiogneisses of the Kurumkan Subgroup, the lengra Group of Aldan Shield are presented. The obtained results show ...
SUPRACRUSTAL SEQUENCES OF THE BELOMORIAN MOBILE BELT: PROTOLITHS, AGE, AND ORIGIN

Myskova T.A.; Glebovitskii V.A.; Miller Yu.V.; L'vov A.B.; Kotov A.B.; Kovach V.P.; Zagornaya N.Yu. (2003)

Two section types are established in the Chupa nappe of the Early Precambrian Belomorian mobile belt (BMB) of the Baltic shield: one in the Lake Verkhnee Pulongskoe area of the stratotype region (Chupa Complex) and the ...
THE U-PB AGE OF THE FEDOROV SEQUENCE OF THE ALDAN GRANULITE-GNEISS MEGACOMPLEX, THE ALDAN SHIELD

Velikoslavinsky S.D.; Kotov A.B.; Sal'nikova E.B.; Glebovitsky V.A.; Kovach V.P.; Zagornaya N.Yu.; Belyaevsky N.A.; Yakovleva S.Z.; Fedoseenko A.M. (2003)

The results of geochronological investigation confirm the assumption of the Early Proterozoic age of Fedorov rock mass. The estimated age (2006±3 mln years) of metaandesite protolytes of this series agrees with age estimates ...
U-PB AGE OF GRANITOIDS IN THE JUNCTION ZONE BETWEEN THE OLEKMA GRANITE-GREENSTONE AND ALDAN GRANULITE-GNEISS TERRANES

Salnikova E.B.; Kotov A.B.; Belyatskii B.V.; Yakovleva S.Z.; Morozova I.M.; Berezhnaya N.G.; Zagornaya N.Yu. (1997)

U-Pb dating of zircons from the reference granitoid complexes showed that principal thrusts in the northern flank of the junction zone between the Olekma granite-greenstone and Aldan granulite-gneiss terranes of the Aldan ...
