-
(1998)A linear potential theory was used for a comparative analysis of tsunami waves excited by piston-type and traveling sea-floor displacements. It is shown that the parameters of these waves depend considerably on the type ...
-
(2001)The poor results of computations concerning the motions of the solid inner core of a slowly rotating, ellipsoidal earth model can be explained by the fact that Smith neglected in the equations of motion second-order terms ...
-
(2002)New material on the Early Bovidae (Hanhaicerus) from Mongolia is described. Phylogenetic relationships between Hanhaicerus and Palaeohypsodontus and other bovids are considered.
-
(2003)Both ancient and modern brachiopods provide examples of how adverse environmental conditions (e.g., in marginal areas and submarine caves, on seamount tops, and in the proximity of hydrothermal fields) result in such ...
-
(1998)Modern nutation theories of the Earth and planets use the assumption, that the planetҳ inertia ellipsoid is symmetrical about the axes of rotation. Below we estimate the effects of the inertia ellipsoid triaxiality accurate ...
-
(2003)A high conductivity zone (HCZ) exists in many places worldwide in the stable mid- to lower continental crust, at the depth of about 20–30 km, but its origin is enigmatic. At this depth range, the temperatures are constrained ...
-
(2004)A new method of modelling scattered seismic pulses is developed, based on the deformation that suffers an initial pulse due to scattering and on a reinterpretation of the product of convolution of a Green function with a ...
-
(2004)Simple cokriging of components of a p-dimensional second-order stationary random process is considered. Necessary and sufficient conditions under which simple cokriging is equivalent to simple kriging are given. Essentially ...
-
(2005)Simple relations are obtained for estimating stresses in the mantle at the time moment of a large meteorite fall from values of the velocity and mass of the meteorite and the sizes of its crater. It is shown that the fall ...
-
(1999)This is a study of the evolution of crustal magma chambers beneath volcanoes driven by the melting of host rocks and the discharge of molten material by eruptions. A qualitative and quantitative description is given for ...
-
(2004)The polarization method for recognition of seismomagnetic waves against a noise background is presented. The method is applied to detection of magnetic oscillations accompanying the propagation of surface Love wave after ...
-
(2000)The motion of plumes through compositionally layered systems is investigated by laboratory experiments in order to understand the ascent modes of deep mantle plumes. Experimental plumes entrain the ambient heavier fluid ...
-
(2002)Notwithstanding an increase in the number of characters used in phylogenetic computer programs, cladograms produced by these methods remain debatable. There is a need to examine the phylogenetic significance of particular ...
-
(2003)An isolated maxillary tooth and opisthocoelous anterior thoracic or posterior cervical vertebral centrum of a duck-billed dinosaur, Hadrosauroidea indet., are described. These parts originate from the marine Albian-Cenomanian ...
-
(2002)New nonmineralized gemmating dimorphic microorganisms have been discovered in the Lakhanda Group at the base of the Upper Riphean (ca. 1.025 Ga) of the Uchuro-Maiskii region of southeastern Siberia. The daughter buds are ...
-
(2003)Body chamber molds of representatives of the genus Proplanulites have been found from the lower part of the koenigi Zone (lower Callovian) of the Kursk Region that contain aptychi of Praestriaptychus koenigi parasp. nov. ...
-
(1989)The analysis of geological and geophysical data on Late-Cenezoic rift zones indicates that the anomalous mantle occurring in asthenospheric upwellings beneath these rift zones has a relatively low density, this being ...
-
(2002)In addition to large amounts of fragmented country rocks, maar-diatreme volcanoes commonly eject juvenile lapilli and cauliflower bombs containing many dispersed xenoliths and/or xenocrysts derived from the country rocks ...
-
(2001)The Fe-Ni metal within chondrites has been postulated to have originated either through condensation or as a byproduct of chondrule formation. To test these hypotheses, we studied metal in three Renazzo-like carbonaceous ...
-
(2003)Osmium-rich Pt group element (PGE) alloys occur worldwide in association with chromite in ultramafic (peridotite) complexes. It has been suggested that these Os-rich alloys formed under extreme P-T conditions in the lowermost ...
