(2003)By means of taxonomically and geochronologically revised species lists (a total of 793 valid species of bivalve molluscs were considered) from 178 formations (‘Suites’) of Neogene and Paleogene deposits in the Russian Far ...
-
(1999)The study of the fossilization processes of modern cyanobacteria provides insights needed to recognize bacterial microfossils. The fossilization of cyanobacteria is discussed and images of recent and fossil bacteria and ...
-
(2001)Southeastern Russia is characterized by considerable potential coal and brown coal resources. Paleogene to Neogene brown coals and Lower Cretaceous bituminous coals appear to be well developed (Khabarovsk, Bazovsky and ...
-
(1989)We chose for investigaton the Koshabulak tectonic structure, within the Sultan-Sandzhar swell, which is one of the group of Pitnyak tectonic uplifts of the Bukhara Bench, which were formed during Hercynian time and continue ...
-
(1989)Mud volcanoes occupy a special place among natural phenomena. First, in terms of the scale of discharges of carbonaceous gases from them, the acute stage of their eruption is comparable to surface lava eruptions from cone ...
-
(1997)The Late Cenozoic volcanic rocks of the East Sikhote Alin are believed to be Pliocene-Quaternary formations by most investigators, even though there is evidence that volcanic activity there began as early as the late ...

(Федеральное государственное бюджетное образовательное учреждение высшего образования «Санкт-Петербургский горный университет», 2017)From 2011 to 2017, large-scale seismic surveys were carried out by PJSC Gazprom Neft within the Pannonian Basin (territory of Serbia). Currently, the coverage area of seismic surveys in the modification of MOGT 3D is ...
-
(1988)Geochemical study of plutonic xenoliths from different regions of the world not only allows the composition of the lithosphere there to be estimated, but also enables the evolution of the upper mantle during geologic time ...
-
(1988)The development of the Kurile island arc is though to have begun in the Late Cretaceous. In the Neogene deposits on northern and southern islands of this ridge, including Kunashir, there are well-rounded fragments of granite ...
-
(2001)The deep structure of the Eurasia-Pacific transition zone was investigated under the Geotraverse International Project along the deep sections of the tectonosphere, including the lithosphere and the asthenosphere, based ...
-
(1987)The paper presents radiologic ages of various volcanic rocks of two regions, the Pontocaspian region and the Greater Kurile Ridge, obtained by track method of dating volcanic ash and tuff that was developed by the present ...
-
(1989)The evolution of exogene copper accumulation can be illustrated by cupriferous sandstones and shales, which are known from the Early Proterozoic to the Neogene, inclusive. Their exogene origin throughout that time interval ...
-
(Федеральное государственное автономное образовательное учреждение высшего образования «Северный (Арктический) федеральный университет им. М.В. Ломоносова», 2019)The respective environments in two ancient rivers were studied using geochemical methods with paleogeographic reconstructions of fossil material represented by shells of freshwater bivalve mollusks. The studied outcrops ...
-
(2004)The isotopic geochronology of a representative collection of moderately acidic volcanics from the Javakheti neovolcanic area in the northwest of the Lesser Caucasus (Georgia) is studied using the K–Ar and Rb–Sr methods. ...
-
(Днепропетровский национальный университет им. Олеся Гончара, 2019)During its long history, the rapids section of the large river the Dnipro not only posed a problem for navigation, but also attracted people with its picturesque rocky landscapes unusual for the Steppe Prydniprovie. Nobody ...
-
(2002)Cenozoic pelagic ('red') clays of predominantly eolian and hydrogenous origin blanket much of the central North Pacific ocean basin. The eolian component is a key indicator of past paleoclimatic conditions; thus, Cenozoic ...
-
(1997)Isotopic composition of Sr, O, Nd, and Pb was determined in K-Na alkaline gabbroids and basaltoids that formed in eastern Kamchatka during Middle Miocene (gabbroids of the subvolcanic complex) and Late Miocene (basaltoids ...
-
(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 ...
-
(2001)Calc-alkaline magmatism in the south-west Ukraine occurred between 13.8 and 9.1 Ma and formed an integral part of the Neogene subduction-related post-collisional Carpathian volcanic arc. Eruptions occurred contemporaneously ...
