(2001)New data on the trace element distribution in rocks of volcanic-plutonic associations from the vicinity of the Karamken gold-silver deposit are reported. The deposit is localized in the outer zone of the Cretaceous ...
-
(2004)The epiplatform (Upper Cretaceous-Paleogene) and neotectonic (Neogene-Quaternary) evolutionary stages and morphostructures are distinguished in Mongolia. The neotectonic structures are characteristic of the orogenic zone ...
-
(1989)Analysis of the evolution of Phanerozoic stratigraphic complexes of the western margin of the East European craton (EEC) and the Central European Platform (CEP) shows that their formation depended on the corresponding ...
-
(1990)The isotopic composition of carbon in oils and condensates of the Chukotka Peninsula was studied in samples taken from wells on the verkhne-Tekelay, Verkhne-Echinskaya, and Izmennaya tracts, located in the southern part ...
-
(1995)Welded tuffs in the Bogopol and Sijanov groups were sampled at 27 sites from 12 caldera formations in the Sikhote Alin mountain range around Kavalerovo (44.3°N, 135.0°E) for chronological and paleomagnetic studies. KAr age ...
-
(2003)Micropaleontology and lithology of rocks dredged near the Terpeniya Rise of the Kuril Basin slope are studied. Bio-, litho-, and seismostratigraphic records are used to distinguish the Paleocene-Lower Oligocene (Seismocomplex ...
-
(2000)This study of minerals from the Late Cretaceous potassic volcanic rocks of the Kirganik Suite from the Sredinnyi Range of Central Kamchatka provided a basis for affiliating these rocks with two series: (1) a plagioclase ...
-
(1997)A detailed study of the Paleogene terrigenous-tuffogenic beds on Kronotskii Peninsula, Govena Peninsula, and in Karaginskii Island and the Komandor Islands has revealed several levels of nannoplankton occurrences, which ...
-
(2002)New data on different organic remains and biostratigraphy of the Paleocene-lowermost Eocene type section in the Indol structural-facies zone of the Indol-Kuban' depression of the Eastern Crimea are discussed. The section ...
-
(2004)Age and spatial relationships between the Gan'kino, Lyulinvor, and Tavda formations, the principal subdivisions of marine Paleogene, are clarified based on comprehensive paleontological study of marine deposits, which have ...
-
(2004)The Paleocene-Eocene marine deposits recovered by two reference boreholes (011BP and 9) in the Omsk depression, the southwestern Siberian plate, have been comprehensively studied in various paleontological aspects. Geology ...
-
(1990)New seismic data obtained by the 'Soyuzmorgeo' All-Union Producing Combine (VMNPO) on the structure of the sedimentary cover and the basement of the Chukchi (Chukotka) Sea have permitted a new approach, differing from ...
-
(2001)Seven new species of Ostracodes are described in six genera. Representatives of the genus Parapokornyella are recorded for the first time in southwestern Crimea, from the Cretaceous/Paleogene boundary beds.
-
(2002)Two new species and one new subspecies of the family Arcidae, i.e., Arca parita, A. nefanda, and A. conformis mandrikovkaensis, from the Paleogene deposits of Ukraine, are described. Several new species of the families ...
-
(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 ...
