(1985)Episodic volcanism favors, as shown by examples from Europe, the USA, and Brazil, the formation of organic-rich sediments (hydrocarbon source rocks). The examples examined from Europe comprise the Lower Carboniferous ...
-
(2003)Four new taxa of the subfamily Brachyericinae, Exallerix manahan sp. nov. (Lower Oligocene of Mongolia), Synexallerix otus gen. et sp. nov. (Lower Miocene of eastern Kazakhstan), Postexallerix securis gen. et sp. nov. ...
-
(2001)The shells of the bivalve genus Fortipecten Yabe et Hatai were found in the Lower Unit of the Maruyama Formation of the Makarov District of Southeastern Sakhalin. Earlier the genus was found only in the middle member of ...
-
(1996)The geology of Iturup Island, which is the largest one in the Kuril island arc, has not yet been considered in any special publications. The island is marked by the occurrence of typical island-arc deposits of the middle ...
-
(2004)Lithology and distribution of nannofossils and mollusks in two continuous sections (anticline of the Mt. Zelenskii, Tamanskii Peninsula, and the Pshekha River section, Western Ciscaucasia) of the upper Chokrakian-lower ...
-
(2004)Two new Early Miocene shrews, Aralosorex kalini gen. et sp. nov. (Altynshokysu, western Kazakhstan) and Miocrocidosorex zazhigini gen. et sp. nov. (Ayaguz, eastern Kazakhstan) of the subfamily Crocidosoricinae are described. ...
-
(1989)Our work gave new paleontologic and radiometric data on the age of the sedimentary, volcanogenic-sedimentary and igneous rocks in the structurally most complex northern part of Bering Island, which supplement existing ...
-
(1990)The shelf deposits off South Vietnam are dominated by Oligocene-to-Miocene clayey carbonate sandstones and argillites, generally resting on a silicic crystalline basement. Penetration of the basement yielded oil flows from ...
-
(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 ...
-
(1998)This article presents the Oligocene and lower Miocene diatom zonation for the North Pacific. The data obtained in Leg 145 of the Oceanic Drilling Program (ODP) allowed a subdivision of Oligocene and lower Miocene deposits ...
-
(2000)The history of hydrologic and faunal changes in the Eastern Paratethys during the middle and late Miocene is briefly outlined. An effort is made to establish the location of straits, through which marine waters penetrated ...
-
(2004)The systematic composition and diversity of Early Chokrakian gastropods, represented by 85 species, are discussed. Twenty species are presumed to be endemic to the Eastern Paratethys, since they are not known for the Middle ...
-
(2000)The paper summarizes paleontological and stratigraphic data on the regional Konkian Stage in the Northern Black Sea, Crimea-Caucasus, and Transcaspian regions. Based on original and published materials, it is shown that ...
-
ORBITAL TUNING AND CORRELATION OF 1.7 M.Y. OF CONTINUOUS CARBON STORAGE IN AN EARLY MIOCENE PEATLAND (2004)Peatland is an important terrestrial carbon reservoir that contains >25% of soil carbon and accounts for 25% 38% of natural methane emissions. Most of this carbon is contained in postglacial boreal peat. Our understanding ...
-
(2000)Phyllonite and metaquartzite clasts occur in early Pliocene or possibly Miocene sediment at the base of the University of Wisconsin Arctic Ocean core Fl-380. Single-crystal 40Ar/39Ar laserprobe ages derived from feldspars ...
-
(2000)Drilling experiments were performed in 1998 on the Akademichesky Ridge at 53 degrees 44'48 " N and 108 degrees 20'34 " E. The borehole depth was 670 m, the water depth was 333 m. Continuous core sampling was performed to ...
-
(1999)The Eocene to Lower Miocene strata in the Bykov region of south Sakhalin Island, Far East Russia, show a mean paleomagnetic direction of Dec. = 28.7°, Inc. = 55.7°, α95=6.7, and N=22, and a paleomagnetic pole at 66.3°N, ...
-
(2001)Palynological characteristics of Eocene-Miocene deposits of the Tatar Strait coast between the Son'e and Dembi bays (eastern Sikhote Alin) are presented. The study spore-and-pollen assemblages and plant imprints show that ...
-
(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 detailed biostratigraphic subdivision of a complete and well-exposed Paleogene-Miocene section in the Ciscaucasia is substantiated on the basis of organic-walled phytoplankton, spores, and pollen. The distinguished ...
