(2001)Present-day approaches to identification of stage and substage boundaries in the Campanian-Maastrichtian of the European paleobiogeographic region (EPR) are considered. A new zonation of the upper Santonian-Maastrichtian ...
-
(2002)The allochthonous northwestern and central tectonic sheets of the Valaginskii Group have been studied in the eastern Kamchatka. Cherty rocks of the Poputnaya and Golubaya sequences yield here abundant radiolarians. The ...
-
(2000)New dating of volcanogenic-siliceous oceanic (marginal-sea) deposits of the frontal Olyutor zone correlative with rocks of the Vatyna Group indicates that, in addition to Albian-Campanian, they include the younger ...
-
(1997)The climate of the Holocene is not well suited to be the baseline for the climate of the planet. It is an interglacial, a state typical of only 10% of the past few million years. It is a time of relative sea-level stability ...
-
(2006)The Omgon Range of Western Kamchatka contains a mid to Upper Cretaceous sequence of flysch with tectonic inclusions of Jurassic-Cretaceous oceanic rocks inferred to have been imbricated together in an accretionary prism. ...
-
(2006)The evolution of Tethyan phosphogenesis during the Cretaceous-Eocene is examined to try to explain fluctuations of phosphogenesis through time, and whether or not they reflect long-term changes in ocean circulation or in ...
-
(2004)The distribution of 218 Campanian marine ostracod genera from 38 geographical areas was used for a quantitative palaeobiogeographical analysis. The data were analysed using multivariate statistical methods, ordination ...
-
(1989)Detailed stratigraphic schemes of the Upper Cretaceous sediments in the Caucasus allowed us to identify the presence of hiatuses and intraformational erosion surfaces based on the omission of one or another stratigraphic ...
-
(2002)Carbon stable-isotope stratigraphy provides unique insights into environmental change during the Campanian, the longest (83.5–71.3 Ma), but least well-understood stage of the Late Cretaceous. A new carbon isotope (δ13C) ...
-
(2006)The Izmir-Ankara-Erzincar suture zone (IAESZ) in the Central and the Eastern Pontides comprises a stack of thrust sheets of mainly Late Cretaceous-Early Cenozoic age that are restored as: (1) a subduction-accretion complex; ...
-
(2004)Latitudinal variations in model biogenic apatite δ18O values were calculated using fractionation equations of vertebrates and weighted rainfall δ18O values along with mean annual air temperatures provided by IAEA–WMO ...
-
(2006)The occurrence of a former subaerial volcanic edifice off the Volturno River (Tyrrhenian Sea, Gulf of Gaeta) in the 41°N parallel is suggested by joint interpretation of multichannel seismic lines and ship-borne magnetic ...
-
(2003)Observations of living Cernina fluctuata (Sowerby), the sole extant species of the Mesozoic and Cenozoic prosobranch gastropod family Ampullospiridae, show that this species is an algal grazer and is not a shell-drilling, ...
-
(1999)The representative radiolarian assemblage different in taxonomy from all known coeval assemblages of Sakhalin was discovered in the basal beds of the Lower Krasnoyarka Subformation of the upper Campanian in the Susuya River ...
-
(2004)A fragmentary proximal epiphysis of a humerus from the Campanian of the Polunino 2 locality (Volgograd Region) belongs to a giant pterosaur, Ornithocheiridae gen. et sp. indet. about 5 m in wingspread. Together with a ...
-
(2006)The fossilized remains of Cretaceous angiosperm leaves are preserved within sandstones and siltstones of the Coniacian Hidden Lake Formation (Gustav Group) and the Santonian-early Campanian Santa Marta Formation (Marambio ...
-
(2006)The major-ion (Mg2+, Ca2+, Na+, K+, multiscripts(SO, 4, mml:none(), mml:none(), 2 -), and Cl-) chemistry of Cretaceous seawater was determined from analyses of seawater-derived brines preserved as fluid inclusions in marine ...
-
(2003)It is difficult to reconstruct the pre-Cenozoic history of western Kamchatka, because Mesozoic deposits are fragmentarily exposed here. The Palana section, the most complete one among Mesozoic sections of the region, is ...
-
(2006)Distribution of belemnites and benthic foraminifers in the Campanian-Maastrichtian boundary layers of the Aktulagai section, one of Upper Cretaceous reference sections in the east of the European paleobiogeographic region ...
-
(2004)Results of multidisciplinary study in the Upper Cretaceous reference section and characteristics of the Mezino-Lapshinovka Formation stratotype are presented. The late Santonian age of the formation is substantiated based ...
