(2003)The Donbas Foldbelt is part of the Prypiat–Dnieper–Donets intracratonic rift basin (Belarus–Ukraine–southern Russia) that developed in Late Devonian times and was reactivated in Early Carboniferous. To the southeast, the ...
-
(2001)The stratigraphic record, distribution and composition of the selachian genus Lissodus is briefly reviewed. 38 species are currently recognised, with 26 further records not designated to species level. Teeth of the genus ...
-
(2001)Application of the lag-time multiple impacts hypothesis [Poag, 1997b. Palaios 12, 582–590; Poag et al., 2001. Columbia Univ. Press] to the Late Devonian leads to the prediction that the Frasnian–Famennian pulsed extinctions ...
-
(1996)Concentrations of the Fe(CO3)OH component in goethites from Phanerozoic oolitic ironstones appear to record information on the partial pressures of soil CO2 in ancient subaerial weathering environments. Application of a ...
-
(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 ...
-
(2001)The Devonian of Belarus has been reviewed. Strata belong to the lower Lochkovian, upper Emsian, and Eifelian through Famennian. Palaeontological data come from palynomorphs, conodonts, ostracodes, brachiopods and fish ...
-
(1996)Stratigraphic evidence indicates that the Russian, or East European, Platform experienced two distinct episodes of long-wavelength down to the east tilting during the Devonian to Permian period. We demonstrate a correlation ...
-
(1998)Tectonic subsidence analysis of five major sedimentary basins of the East European platform reveals two episodes of rapid downward motion since the Devonian. The mechanisms of basin evolution are examined to explain the ...
-
(2003)Forward and reverse modelling of structure and stratigraphy has been used to investigate the syn-rift (Late Devonian) and early post-rift (Carboniferous) evolution of the south-eastern part of the Dniepr–Donets Basin (DDB). ...
-
(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 ...
-
(2001)We reinterpret the regional ge logic setting of the giant Muruntau gold deposit and report new 40Ar/39Ar isotope age determinations and a laser Raman microprobe analysis of fluid inclusions. New 40Ar/39Ar isotope age ...
-
(Федеральное государственное бюджетное образовательное учреждение высшего образования «Санкт-Петербургский горный университет», 2018)The Devonian rocks exposed on the shores of Lake Il’men, some 150 km SSE of Saint Petersburg, are important historically in the context of the recognition of the Devonian System. Moreover, they provide unique potential for ...
-
(2001)In the Baltic region, Devonian sedimentary bedrock is exposed in a wide area extending from north-eastern Estonia through Latvia to the south-eastern Baltic Sea. Westwards in the Baltic Sea, the outcrop terminates against ...
-
THE LOWER CRUST OF SE BELARUS: PETROLOGICAL, GEOPHYSICAL AND GEOCHEMICAL CONSTRAINTS FROM XENOLITHS (2001)Highly altered alkaline lamprophyre tuffs of Devonian age from SE Belarus contain lower crustal xenoliths that vary from feldspar-rich mafic granulites to rarer feldspar-poor eclogitic granulites, together with coarse-grained ...
-
(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 ...
-
(2001)The origin of tetrapods from sarcopterygian fish in the Late Devonian is one of the best known major transitions in the history of vertebrates. Unfortunately, extensive gaps in the fossil record of the Lower Carboniferous ...
-
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 ...
-
(2001)The cranial anatomy of Orlovichthys limnatis, a Famennian, Late Devonian dipnoan from the Orel region of central Russia, is described on the basis of an almost completely preserved skull, a mandible, and numerous elements ...
-
(2001)The vertical cross section and evolution of the major mineral phases were studied in the Layeredcomplex of the Late Devonian Voikar ophiolite association. The complex consists of two megarhythms sepa-rated by a transitional ...
