(2002)The Upper Cretaceous sequence in the east of the Lesser Caucasus, within the Azerbaijan territory, begins with the Cenomanian terrigenous sediments that are overlain with a hiatus by thick volcanogenic-terrigenous deposits ...
-
(1994)Maastrichtian tuffaceous sandstones and siltstones were sampled from four sites in the northern part of Shikotan Island in the Lesser Kuril Islands. A characteristic component (ChRM) isolated from most samples passes the ...
-
(2003)Time-stratigraphic patterns of stable carbon isotopic ratios recorded in terrestrial organic matter from Cenomanian-Maastrichtian successions for the Russian Far East can be correlated to those of carbonate carbon from ...

(2004)Time-stratigraphic patterns of stable carbon isotopic ratios recorded in terrestrial organic matter from Cenomanian–Maastrichtian successions for the Russian Far East can be correlated to those of carbonate carbon from ...
-
(2004)The Baikal region is located in a single climate zone and includes the Baikal foredeep on the eastern margin of the Siberian craton and the Baikal rift evolving at the western boundary of the Baikal orogenic area. Late ...
-
(1990)The following representative radiolarian assemblages are known in the Greater Caucasus: Callovian-Oxfordian, Tithonian, Albian-Cenomanian, Lower Turonian, Upper Turonian-Santonian, and Campanian-Masstrichtian. The discovery ...
-
(1997)The effect of surface seismic disturbances induced by cosmic gravitational radiation is considered. A brief review of previous results is included. A spherically symmetric homogeneous isotropic Earth model with a four-component ...
-
(2003)We present new results on the structure resulting from Palaeoproterozoic terrane accretion and later formation of one of the aulacogens in the East European Platform. Seismic data has been acquired along the 530-km-long, ...
-
(2001)We introduce a method to infer upper mantle azimuthal anisotropy from the polarization, i.e., the direction of particle motion, of teleseismic long-period P onsets. The horizontal polarization of the initial P particle ...
-
(2001)Although much progress has been made in determining the 3-D distribution of seismic wave velocities in the Earth, substantially less is known about the 3-D distribution of intrinsic attenuation. In this study variations ...
-
(1965)The southern part of the Kuril Islands is typical of an island arc. The structure of the earth's crust in that region has been well studied by seismic sounding. The present paper gives a short synthesis of data about the ...
-
UPPER MANTLE STRUCTURE BELOW THE DALDYN-ALAKITSK KIMBERLITE FIELD BY NUCLEAR EXPLOSION SEISMOGRAMS (2001)It was established on the basis of seismograms of nuclear explosions that the upper mantle up to the depth of 410 km is characterized by chemical differentiation, which occurs as alternating layers with low and high body ...
-
(2003)A new teleseismic tomography approach (RR-R scheme), based on joint processing of differential travel times of P or S refracted rays and corresponding PP or SS rays with bounce points in a selected area, allows three-dimensional ...
-
(1999)Forward numerical models are used to investigate the effect of deformation regime on the development of olivine lattice-preferred orientations (LPO) and associated seismic anisotropy within continental deformation zones. ...
-
(2000)The Upper Mesozoic strate of the Korean Peninsula are subdivisible into three unconformity-bounded units, and they developed time-transgressively toward the Pacific. The lower unit straddling the Jurassic-Cretaceous boundary ...
-
(2004)Late Oligocene basins were very unusual in terms of sedimentation. The most remarkable example is the early Kalmykian basin that was characterized by the drastic morphological differentiation and deposition of substantially ...
-
(2004)Upper Oligocene sediments of the Eastern Paratethys are distinguished in the Maikop Group owing to several characteristic features. They form a thick (1000–1200 m) sequence with specific composition and structure in different ...
-
(2004)The structure of bone detritus and iron sulfide deposits is scrutinized based on the abundant analytical data on their component composition and metal potential. It is shown that maximal concentrations of bone detritus and ...
-
(2004)The Upper Ordovician (uppermost Caradoc-Ashgill) section of western Estonia consists of a series of seven open-shelf carbonate sequences. Depositional facies grade laterally through a series of shelf-to-basin facies belts: ...
-
(2003)The analyzed materials obtained by editorial preparation of a new map series, scale 1 : 1 000 000, and generalization of earlier data show that, contrary to prevailing opinions, the Middle to Upper Carboniferous deposits ...
