-
(1997)The crustal structure and lithospheric flexure of the Baikal Rift Zone, Siberia, are examined by means of gravity modelling. We model the Bouguer Anomaly (BA) along five 1200 km long gravity profiles. We first evidence ...
-
(2001)We report an experimental and theoretical study of non-linear Arai–Nagata diagrams for samples containing pseudo-single-domain (PSD) and multidomain (MD) magnetite. Our aim is to reveal the physical reasons for the deviation ...
-
(2004)The type species of the genus Conispirifer Ljaschenko, C. rotundus Ljaschenko, is revised based on the material from the Upper Devonian of the southern Timan. C. rotundus was established based on juveniles of Tenticospirifer ...
-
(2003)Three different classifications of the family Berriasellidae are revised. The phylogeny of the genera Euthymiceras Grigorieva, 1937, Gechiceras Sach., 1982, Transcaspiites Luppov, 1985, and Riasanites Spath, 1923 is ...
-
(2001)Quantitative data on the finds of bony remains of Late Jurassic and Early Cretaceous marine reptiles in the Volga Region near Ulyanovsk are given. A taphonomic classification of ichthyosaurian fossils and the probable ...
-
(2002)The morphogenesis of the genus Borissiakoceras is studied on the basis of material from the Taimyr Peninsula. The stratigraphie and geographic distribution of the genus are discussed, and a systematic description is provided.
-
(2002)Based on the examination of cervical vertebrae 1-4, a new species, Samotherium borissiaki sp. nov., from the Meotian of the Taraklia locality (Moldova) is described. The first and second vertebrae are of special interest, ...
-
(2004)Conifers of the genus Tritaenia Mägdefrau et Rudolf are reported for the first time from European Russia. The locality of Peski (Middle Jurassic, Moscow Region) contains two newly described species, T. striata sp. nov. and ...
-
(1997)The time variation of background seismicity was studied in the Gulf of Avacha, Kamchatka, where a M 7.75 earthquake had earlier been predicted to occur. An analysis of detailed seismological observations conducted for 33 ...
-
(2005)Extraction and electron irradiation (under transmission electron microscopy) of an epitaxial nanometer-thick α-PbO2-type TiO2 slab between twinned rutile bicrystals in ultra-high pressure metamorphic rock caused phase ...
-
(1998)Uranium-lead analyses that yield arguably concordant U/Pb and Pb/Pb ages are highly reliable and often very precise; however, there is no generally accepted way for either assigning a best age and age-error or for evaluating ...
-
(2001)By using Molodensky and Sasao (1995a) and Molodensky and Groten (1998) an approach of expansion in powers of the small parameter =(+)/ (where + and are the frequencies of nutational motion in space and in a mantle-fixed ...
-
(1980)Review of the distribution of the U.S.S.R. Upper Precambrian stromatolites in time and space demonstrates an unrepeated and unidirectional change of their assemblages along with distinct lateral differentiation of the ...
-
(1998)The results of joint fieldwork with geologists from the Geological Survey of Norway refine the Upper Proterozoic correlation scheme for the Barents Sea region and substantiate recognition of three structural-facial zones: ...
-
(2005)The melt-filled pore structure in the final stages of solidification of cumulates must lie somewhere between the two end-members of impingement (in which pore topology is controlled entirely by the juxtaposition of growth ...
-
(2002)We propose to deepen the interpretation of combined geophysical methods (georadar, seismic and electric) to assess physical properties characterizing the near-surface porous formations, especially the influence of water. ...
-
(2001)We report the results of a comparative thermomagnetic investigation on natural volcanic samples. Susceptibility vs temperature (k–T curves), induced magnetization vs temperature and remanent (saturated) magnetization vs ...
-
(2002)Increasing attention has been paid to the use of non-Gaussian distributions as models of heterogeneity in sedimentary formations in recent years. In particular, the Levy-stable distribution has been shown to be a useful ...
-
(2001)Electrical resistivity mapping was conducted to delineate boundaries and architecture of the Eumsung Basin Cretaceous. Basin boundaries are effectively clarified in electrical dipole-dipole resistivity sections as ...
-
(2003)Earthquake forecasting is one of the geophysical issues with a potentially large social and political impact. Besides the purely scientific interest, the loss of lives and the huge damage caused by seismic events in many ...
