(2000)Three stratigraphic type areas (the Moiero River vicinity, Turukhansk and Noril'sk districts), where clayey-carbonate sedimentary facies are widespread, characterize the Silurian of East Siberia. The Moiero River neighborhood ...
-
(2003)In the Silurian-Carboniferous (440-330 Ma), the Urals was involved in suprasubduction magmatism. The following subduction-related intrusive magmatites are recognized here: 1. Volcanic, mainly high-level complexes including: ...
-
(1998)Carbonate-phtanite sediments of Bogambir suite (Uppermost Precambrian, Northern Nuratau Mountains, Uzbekistan) are to be discriminated from Ordovician and Silurian in the imbricated Variscian structure of Bogambir range. ...

THE AGE OF CHOKUSU BEDS IN THE KYZYL-DZHAR-CHOKUSU SECTION (THE SILURIAN OF NORTHWESTERN MONGOLIA) (2000)The rock succession and age of the Chokusu Beds in the Mt. Kyzyl-Dzhar-Chokusu section is considered to be either the Ludlovian-Pridolian or Wenlockian-early Ludlovian. The discrepancy resulted from a complicated geological ...
-
(2003)The problem of an 'Armorica microplate', detached from Gondwana and having had during part of the Palaeozoic an independent latitudinal evolution, is reconsidered in terms of a critical review of the palaeomagnetic data ...
-
(1999)The bed-by-bed standard of the Silurian for East Siberia is used to correlate stratigraphic sequences all over the Siberian platform and Taimyr. Fossil faunas and floras of the standard are very representative, because the ...

-
(2001)According to conventional ideas, numerous eustatic sea-level changes occurred during the Phanerozoic with amplitudes 20–100 m and periods T=1–3 Myr (third-order cycles). At the same time, it is widely recognized that ...
-
(1996)Land plants and their associated microbiota directly affect silicate mineral weathering in several ways: by generation of chelating ligands, by modifying pH through production of CO2 or organic acids, and by altering the ...
-
(2001)The Kola-Kanin Monocline has been recently recognized as a potentially prospective region for hydrocarbon discoveries. There may be good generating potential within Riphean grabens. Sedimentary sequences of the Riphean ...
-
(2003)Pure quartz arenites are especially characteristic of lower Paleozoic and Proterozoic strata deposited in nonorogenic settings. A century-long debate over the origin of these remarkably pure sandstones has remained unresolved, ...
-
(1997)The Ludfordian sections of shallow-water carbonates, which are exposed in the Urals, Arctic islands, and northeastern part of the East European platform, yielded diverse brachiopod assemblages (BA-2) with dominant atrypids ...
-
THE NATURE OF SEA DEPTH CHANGES IN EPICONTINENTAL SEDIMENTARY BASINS OF EAST SIBERIA IN THE SILURIAN (2004)It is commonly recognized that sea level experienced strong global-scale systematic changes in the geologic past. Its 20-100 m fluctuations in 1-10 m.y. (third-order) cycles are most often detected using Fischer plots based ...
-
(1992)The Caledonides of Ny Friesland comprise the type Hecla Hoek sequence of Svalbard, a succession of late Proterozoic to Ordovician strata greater than 18 km thick. Three supergroups constitute the sequence: the Stubendorffbreen ...
-
(2002)Silurian palaeobiogeography of the Ramphoprionidae (Annelida; Polychaeta) is outlined. Members of the family are reported from northern Europe (Estonia, Sweden and England), the Russian Arctic (Severnaya Zemlya), and the ...
-
THE REFERENCE SECTION OF SILURIAN-LOWER DEVONIAN BOUNDARY DEPOSITS IN THE EASTERN SLOPE OF THE URALS (2000)Carbonate and volcanogenic-sedimentary deposits composing the upper Pridolian Substage and Lochkovian stages in the area between Boksity Station in the south to the Sos'va River in the north (eastern slope of the northern ...
-
(2006)Reported in this paper are the results of the analysis and generalization of the geological, radiometric, paleomagnetic and biogeographical data obtained in the Western, Central, and Eastern Tien Shan during the study of ...
-
(2014)The Central Asian Orogenic Belt (CAOB) consists of many tectonic terranes with distinct origin and complicated evolutionary history. Understanding of individual block is crucial for the reconstruction of the geodynamic ...
-
(2000)Месторождение является продуктом контактового метасоматоза, при котором обменный процесс осуществлялся объем на объем (вынесенный суммарный объем кремния, кальция, алюминия, магния компенсировался таким же объемом магнетитового ...
