(2001)New taxa of benthic foraminifers from the order Nodosariida are described: Turkmenicaellinae subfam. nov.; Dolosia gen nov.; D. alpha sp. nov.; Hydromylinella gen. nov.; H. wittpyuti sp. nov., H. plana sp. nov.; and ...
-
(1989)In East Kamchatka, Cretaceous oceanic rocks are known on the Cape Kamchatskiy peninsula and in the melange zones of the East Ranges. The authors' investigations in 1985-1987 revealed oceanic rocks in the eastern part of ...
-
(2004)An assemblage of Lower Eocene nummulitids is established here for the first time from the Sullukapian Formation, which has been referred to the Upper Paleocene. A new species, Nummulites akorpensis sp. nov., which was ...
-
(1990)Our study of bryozoans has enabled us to date the Cretaceous-Paleogene boundary deposits more reliably. Of particularly great interest are the bryozoans from two sections far apart, where they occur in mass quantity: in ...
-
(1998)Krassilov wrote in the beginning of his book (1989), that nearly all eminent botanists considered it their duty to speak on the problem of angiosperm origin. Conse- quently, as an entomologist, because of the close asso- ...
-
(2003)The genera Ameghinoia Viana et Haedo Rossi and Polanskiella Rossi de Garcia are synonymized under Archimyrmex Cockerell, which now includes three species, A. rostratus (Middle Eocene, United States), A. piatnitzkyi (Upper ...
-
(2003)New data on the taxonomic composition, geographic and stratigraphie occurrence of Paleogene ciliates and problematic microfossils in the southern former Soviet Union are discussed. New taxa of tintinnid ciliates, Tianella ...
-
(1996)Analysis of the Paleogene planktonic foraminifers from the sections of Kamchatka, Koryak Highland, the North Pacific, and Japan revealed several age levels of the occurrences of warm-water (subtropical) assemblages: late ...
-
(1999)The Oligocene Leporidae from the Zaisan Depression (Eastern Kazakhstan) collected by the Joint Kazakhstan-American Paleontological Expedition during 1993 and 1994 are described. A new genus and species of the family ...
-
(1997)The taxonomic composition of planktonic foraminifers from the relatively complete Paleogene sections first recovered by deep-sea drilling in high latitudes of the North Pacific allowed these deposits to be dated and ...
-
(1997)Results of the litho- and biostratigraphic studies of core samples from more than 40 deep oil and gas prospecting wells drilled in the Kolpakovka depression in the 1980s and 1990s were considered. The lithology of Paleogene ...
-
(2002)Several conflicting explanations, invoking persistent non-dipole fields or tectonic motion on various scales, were suggested to account for anomalously low paleomagnetic inclinations in Cenozoic rocks of Central Asia. In ...
-
(1997)Palynological data are used for the first time to subdivide in detail the Paleogene-Miocene deposits filling intracontinental depressions in the Amgun-Gorin region. Twelve pollen assemblages are distinguished in the composite ...
-
(1999)The antidromous and most acid series of a volcanoplutonic belt in the Southeastern Pamirs was studied. It makes up a stratovolcano 1365-3150 m thick and consists of five volcanogenic formations (rhyodacites, trachydacites, ...
-
(2001)Comprehensive Petrological and geochemical studies of Albian, Late Senonian and Paleogene volcanogenic basalt-bearing formations of the Chukchi segment of the Okhotsk-Chukchi volcanic belt (CS OCVB) were carried out using ...
-
(1995)A numerical model which describes oxygen isotope exchange during burial and recrystallization of deep-sea carbonate is used to obtain information on how sea surface temperatures have varied in the past by correcting measured ...
-
(2001)Two isolated molars, the holotypes of Asiaparamys shevyrevae NESSOV, 1987b and Kazygurtia clivosa NESSOV, 1987b from the latest Paleocene Dzhylga 1 a locality are restudied, and an additional molar of A. shevyrevae from ...
-
(1988)The rubidium- and strontium-isotope distribution in volcanic rocks of the shoshonite-latite series of Bulgaria has never before been investigated. The Borovitsa volcanotectonic depression studied by us is underlain by rocks ...
-
(2005)This paper presents new data for the geological structure of South Sakhalin which is a connecting link between the structural features of the Sakhalin and Hokkaido islands which form the Late Mesozoic-Early Cenozoic ...
-
(1996)The modern substantiation of the boundaries in the Phanerozoic scale of geologic time is discussed with reference to absolute geochronology. The critical analysis of the isotopic-geochronologic data that form the basis of ...
