Autor: K. A. Savko, O. M. Turkina, A. D. Nozhkin
Publikováno v: Russian Geology and Geophysics. 62:1175-1187
—The paper presents results of a petrogeochemical and isotope–geochronological study of the granite–leucogranite association of the Pavlov massif and felsic volcanics from the Elash graben (Biryusa block, southwest of the Siberian craton). A ch

Publikováno v: Doklady Earth Sciences. 497:286-290
The age of carbonate rocks of the Tim Formation of the Oskol Group of the Kursk block, Sarmatia, is limited to 2.22–2.10 Ga on the basis of new data on δ13C and 87Sr/86Sr. Carbonate rocks with an anomalously high value of δ13С (about +11‰ V-PD

Paleoproterozoic OIB- and MORB-Type Rift Volcanics of the Kursk Block, Eastern Sarmatia: Petrology and Geodynamics
Autor: A. V. Samsonov, K. A. Savko, S. V. Tsybulyaev, E. H. Korish
Publikováno v: Petrology. 29:114-147
The metabasites of the Tim Formation occur in the Paleoproterozoic Orel, Tim–Yastrebovka, and Avilsky synforms in the Archean Kursk block of Eastern Sarmatia. The volcanics are picrites, picrobasalts, basalts, and basaltic andesites metamorphosed t

Age Benchmark of Granulite Metamorphism in the Angara–Kan Block, South Yenisei Range: Evidence from Zircon Dating of Postcollisional Granite–Aplite Dikes
Autor: Igor I. Likhanov, K. A. Savko, P. S. Kozlov
Publikováno v: Geochemistry International. 59:206-211
The paper presents isotope–geochronological data on zircons from a granite–aplite dike that cuts garnet–hypersthene gneisses of the Kuzeyev unit of the Neoarchean–Paleoproterozoic Kan Group in the southern extension of the Ishimba–Tatarka r

The Paleoprotherozoic Volcanics of the Tim Formation within the Kursk Block, Sarmatia: Age and Geodynamic Setting
Autor: E. Kh. Korish, K. A. Savko, S. V. Tsybulyaev, A. V. Samsonov
Publikováno v: Doklady Earth Sciences. 495:831-834
The volcanic–terrigenous Tim Formation in the Kursk Block of Sarmatia occurs in the Paleoproterozoic synforms. The Tim Formation volcanics are represented by metamorphosed ferropicrites, ferropicritic basalts, basalts, and andesibasalts. According
