(2004)A new form genus, Pseudotsugoxylon, is designated to include fossil woods with anatomical characters typical of extant Pseudotsuga. The material came from the Pliocene of the Pavlovka lignite field (southern Primorskii ...
-
(1988)Finds of garnet peridotite xenoliths in Cenozoic volcanics are fairly rare. Until recently, only three such finds were known on the Vitim plateau, in Pliocene rocks of the Kandiduskha and the Yasha paleo-volcanoes. We give ...
-
(1988)To obtain more complete petrological information, we thoroughly studied volcanic rocks of the Sovetskaya Gavan complex in the Koppi River basin on the Sovetskaya Gaan' Plateau and along upper reaches of the Samarga River ...
-
(2000)Three series of peridotite xenoliths from basanites of the Dzhilinda River were analyzed. The trace-element patterns of clinopyroxenes of Iherzolites of series 1 and 2a correspond to low-degree partial melting of the ...
-
(2001)The highest and longest ridges of the East Yakutian mountainous province exist on its periphery as the Verkhoyansk system in the west and the Chersky and Moma systems in the east. Northward, the ridges give way to the ...
-
(2001)The Pliocene and Pleistocene sediments exposed in eight sections of Transbaikalia have been correlated using geological and palynological data, together with information on fossil mammals and some paleomagnetic characteristics. ...
-
(1997)Thermal structure of the crust beneath the Domandorsky Basin was modeled in the context of its tectonic evolution as a result of backarc rifting processes. The good fit of the theoretical heat flow to the results of heat ...
-
(2001)As part of an effort to try to halt the decline in onshore oil production and accelerate production from onshore fields in Azerbaijan, a World Bank-sponsored study of four fields was carried out: the Bibi-Eybat, Kala, ...
-
(1988)The authors studied ten peridotite inclusions from basalts of the central Vitim Plateau namely eight granite-containing and one spinel-containing 1herzolite from recently discovered alkalic picrite tuff, thought to be of ...
-
(2001)This study is based on the isotope-geochemical characteristics of oils from 53 fields in the South Caspian Basin - from Upper Cretaceous, Eocene, Oligocene-Lower Miocene (Maykop), middle and the Upper Miocene (Diatom) and ...
-
(1996)For the purpose of the geological mapping of Cenozoic volcanic rocks in South Kamchatka, K-Ar ages of the rocks were determined using 30 whole rock samples. The rocks of the andesite association were found to be of the ...
-
(1999)Medvezhiya caldera is a polygenetic volcanic structure including the Medvezhii, Srednii, Kudryavyi, and Menshoi Brat volcanoes and several flood basalt vents. The discovery of a new volcano, Tukap, with a rhenium ore ...
-
(2001)The data on the successions of the Late Miocene - Pliocene mammalian faunas from the territory of the former Soviet Union and Mongolia are summarised. The main characteristics of the MN zone for these territories are given.
-
(2002)Geochemical data on Late Cenozoic within-plate basalts from the southern part of the Russian Far East are utilized to demonstrate the main features of the lithospheric structure in the continent-ocean transition zone and ...
-
(2001)Within the framework of the Baikal Drilling Project (BDP), a 192 m long sediment core (BDP-96-1) was recovered from the Academician Ridge, a submerged topographic high between the North and Central Basins of Lake Baikal. ...
-
(2002)Palynomorphs from a palaeomagnetically dated Late Pliocene sediment core (3.6–2.35 Ma) reflect highly variable climatic conditions and repeated expansion of steppe and boreo-alpine vegetation. Mixed coniferous forests ...
-
(2002)A fossil of Libralces gallicus Azzaroli from the Khaprovian beds of the Liventsovka locality (lower course of the Don River, Middle Villafranchian) is redescribed. The proportions of the antler beams and small measurements ...
-
(2002)The nature and magnitude of climatic variability during the period of middle Pliocene warmth (ca 3.29–2.97 Ma) is poorly understood. We present a suite of palaeoclimate modelling experiments incorporating an advanced ...
-
(1986)The development history of the Alpine-Carpathian segment of the Alpine belt is considered. Since the Triassic numerous deep basins on continental crust have been formed there by rapid subsidence without significant stretching ...
-
(1988)This article sums up the second stage of work on devising a Late Cenozoic radiometric time scale for the eastern Paratethys, in which we initially dated Sarmatian deposits of Moldavia and the Kerch'-Taman' region. Radiometric ...
