-
(1989)The correlation between compositions of metasomatites and conjugate ore mineralization has already been analyzed for various ore and metasomatic rock associations, formed at different depths. Here the authors illustrate ...
-
(1990)In the present paper, we shall identify correlations between the invariants of the hydrodynamic processes in lakes and the characteristics of the perturbation-producing sources.
-
(2005)We investigated the influence of thermal maturity on the hydrogen isotope ratios of sedimentary hydrocarbons to prove that the isotope ratio of hydrocarbons mirrors paleoclimate signatures. δD values from n-alkanes and ...
-
(1989)The question regarding the influence of the abundance of a chemical element on the total number of its mineral species has attracted the attention of researchers. At the present time, more complete statistical data on the ...
-
(2006)Correlation migration for structural imaging using Gaussian beams is described for the inversion of passively recorded teleseismic waves. Gaussian beam migration is based on an overcomplete frame-based representation of ...
-
CORRELATION OF ALBIAN RADIOLARIAN ASSEMBLAGES FROM THE GREATER CAUCASUS, EUROPE, AND MEDITERRANEAN (2002)Generalized data on Albian radiolarians from the Greater Caucasus refine composition of their Spongostichomitra elatica (middle Albian) and Dictyomitra disparlita-Crolanium triangulare (upper Albian) assemblages. The ...
-
(2002)The paper reports the results of complex studies of core samples of Archean rocks from the Kola Superdeep Borehole and analogues of these rocks collected at the surface. The analogy of these rocks is justified by the ...
-
(2003)The irreversible evolution of the Earth and periodic fluctuations of the climate and environment are major forces that drive biological evolution. Irreversible evolution is exemplified by the cooling of the Earth's interior, ...
-
(2002)Some Triassic key sections of Siberia and the eastern Urals are characterized in terms of paleontology. In the northeastern Siberia, these are sequences of the Cape Tsvetkov (the eastern Taimyr Peninsula) and the Ust'-Anabar ...
-
(2004)Upper Devonian clastic complexes (the Zilair Formation flysch, Biyagoda mixtite, Koltuban limestone conglomerate, Bugodak volcanogenic-sedimentary sequence) are considered. In the eastern flank of the Southern Urals, the ...
-
(1987)There exists a definite relationship between type of the geomagnetic field and the individual stages of megacycles of the Earth's evolution. Based on their experimental data, the authors draw the following conclusions: (1) ...
-
(2003)Composite stratigraphic sections of Lower-Middle Jurassic (pre-Callovian) deposits, which have been studied in the northern, axial, and southern parts of the Greater Caucasus central segment are described. Stratotypes and ...
-
(1997)Based on the analysis of sections of the southeastern Sikhote Alin (Primor'e), it is inferred that the subdivision and mapping of chaotic olistostrome complexes by traditional stratigraphic methods is impossible. ...
-
(2002)Isotopic data of unaltered low-Mg calcite brachiopods from type Bashkirian strata of the Askyn River section (southern Urals, Russia) are correlated with those from the Mid-Carboniferous Boundary Global Stratotype Section ...
-
(2004)The marine sedimentary successions of Barremian age yield, both in northwest Europe and on the Russian Platform, diverse and abundant belemnite faunas. These include the genera Praeoxyteuthis, Aulacoteuthis and Oxyteuthis ...
-
(1997)Detailed Paleogene stratigraphy is based nowadays on the zonal schemes of different microfossil groups. The specific character of their development and the use of microphytofossil zonations in the regional stratigraphy of ...
-
(2006)Trend of climatic changes in geological history of the Earth was determined by gradual decrease in the global surface temperature. Substantial deviations from this trend depended on the prevalent type of volcanism: ...
-
(1998)The analyzed distribution ranges of tetrapods, ostracods, megaspores, and other fossils were used, with due regard for the facial dependence and phylomorphogenetic lineage, to resolve correlation problems concerning Triassic ...
-
(2003)Composition and structure of the Upper Neopleistocene alluvial and lacustrine sections in the southern trans-Urals region are discussed. Sections of the Kamyshlov alluvial complex (Streletskoe, Vvedenskoe, Verkhnyaya ...
-
(1999)The Upper Mesozoic deposits of the northern and southern parts of the Korean Peninsula significantly differ from each other. The Upper Jurassic-Neocomian deposits of North Korea are represented by the differentiated volcanics ...
