Behavior of Trace Elements in Rock-Forming Minerals during Partial Melting and Migmatization of Granites in the Aldan Shield

Autor: I. S. Sedova, V. A. Glebovitsky

Publikováno v: Geology of Ore Deposits. 60:658-671

The evolution of rock-forming minerals (orthopyroxene, garnet, biotite, and amphibole) is studied in successive generations of granites and leucosomes. It is shown that the trace element partition coefficients between solid phases and melt are govern

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

Publikováno v: Doklady Earth Sciences. 476:1143-1146

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

Geochemistry of biotite from charnockitoids in the granite-forming series (Nimnyr Block of the Aldan Shield)

Autor: V. A. Glebovitskii, Sergey G. Skublov, I. S. Sedova

Publikováno v: Doklady Earth Sciences. 470:1076-1080

The geochemical evolution of biotite (Bt) from garnet-bearing associations in the granite-forming series of the Nimnyr Block (Aldan Shield) is considered. The series includes the primary rock (gneiss or basic rock), autochthonous enderbite- or charno

Distribution of REE, LILE, and HFSE between biotite, feldspar, and the melt in the granulite facies migmatite, nimnyr block, Aldan shield

Autor: I. S. Sedova, V. A. Glebovitskii

Publikováno v: Doklady Earth Sciences. 466:165-168

The behavior of trace elements under conditions of partial melting of granitoid rocks has been studied. The element’s partition coefficients between minerals and the melt D min/melt depends, in the first place, on the composition of the primary mel

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

LILE, REE, and HFSE partition coefficients between crystal and melt in migmatites of granulite facies of the Nimnyr block, Aldan shield

Autor: I. S. Sedova, V. A. Glebovitskii

Publikováno v: Doklady Earth Sciences. 462:487-493

The behavior of Rb, Sr, Ba, Cr, V, Nb, Zr, REEs, and Y is studied in migmatites of granulite facies and the transitional zone to amphibolite facies in the western part of the Aldan granulite area. Our data allowed estimation of the partition coeffici

Peculiarity of ultrametamorphism in the juncture zone of the Aldan shield and Dzhugdzhur-Stanovoi folded area

Autor: V. A. Glebovitsky, I. S. Sedova, L. M. Samorukova

Publikováno v: Geochemistry International. 50:619-637

The processes of ultrametamorphism in the juncture zone between the Aldan shield and Stanovoi folded area are manifested in granitization (volume-for-volume replacement of gneisses by trondhjemite gneisses Lc1) and subsequent migmatization with forma
