-
(2002)The concept of apparent susceptibility can be extended to bodies with arbitrary geometry by considering the integrated magnetization or dipole moment associated with the body. This unique characteristic can be easily ...
-
(2001)A palaeomagnetic study of the Vepsian sandstones of the upper part of the Shoksha Formation has revealed a stable remanence. Rock magnetic and mineralogical studies suggest diagenetic haematite as the main carrier of this ...
-
(2004)The phase relationships contained in the magnetotelluric (MT) impedance tensor are shown to be a second-rank tensor. This tensor expresses how the phase relationships change with polarization in the general case where the ...
-
(2003)Several ethological-trophic groups of the marine benthic organisms are established. The changes in the taxonomic composition of these groups and their significance are studied for the period from the Cambrian to the Recent. ...
-
(2004)This chapter discusses the latest modifications to the glacial pattern in Belarus in comparison to the 1980 Geomorphological Map. On the basis of the results of recent investigations, the glacial pattern in Belarus was ...
-
(2001)As a result of the intensive movement of the cytoplasm through the aperture when communication with the environment is required, this area has an important and variable functional burden. Additional skeletal structures ...
-
(2003)The paper contains results of geological, structural, mineralogical, isotopic, and thermobarogeochemical studies of one of the few known gold deposits in the Early Proterozoic greenstone belt of North Karelia. The Maisk ...
-
(2004)A study of the sequence and stages of the mineral-forming processes, chemical compositions of sulfides, fluid inclusions, and sulfur isotopes in sulfides and oxygen isotopes in quartz of the Maiskoe deposit has been carried ...
-
(2003)During the Neoproterozoic, a supercontinent commonly referred to as Rodinia, supposedly formed at ca. 1100 Ma and broke apart at around 800–700 Ma. However, continental fits (e.g., Laurentia vs. Australia–Antarctica, Greater ...
-
(1999)The Manzurka Alluvium fills ancient valleys of the Baikal-Lena watershed. Previously, the sequence of the constrative alluvium was considered to be of the Eopleistocene age. Latest investigations showed that despite the ...
-
(2003)Osmium (Os) isotope analyses of bulk sediments from the South Atlantic, Equatorial Pacific, and the Italian Apennines yield a well-dated and coherent pattern of 187Os/188Os variation from the late Eocene to the early ...
-
(2002)Loess-palaeosol sequences from the western part of the East European loess province were palaeomagneticaly studied. The position of Matuyama-Brunhes boundary was found in the sequence at Zahvizdja (East Carpathian Foreland) ...
-
(2003)Considering the magnitudes of events in a catalog as independent and exponentially distributed random variables, in agreement with the Gutenberg–Richter law, the statistical significance of the difference between the maximum ...
-
(2002)The remarkable fact about the Mazapil meteorite is that it fell on the same night, in 1885, that the Andromedid meteor shower underwent a spectacular outburst. The simultaneity of these two events has driven speculation ...
-
(2002)Sorption processes can be used to study different characteristics of coal properties, such as gas content (coalbed methane potential of a deposit), gas diffusion, porosity, internal surface area, etc. Coal microstructure ...
-
(1997)We measured oxygen fugacities in H2-CO2 and CO-CO2 gas mixtures in the temperature interval 700-1350°C using an yttria-stabilized zirconia (YSZ) oxygen sensor. At high temperatures in excess of 1200°C, measured emfs are ...
-
(2004)At T > 100°C development of thermodynamic models suffers from missing experimental data, particularly for solubilities of sulfate minerals in mixed solutions. Solubilities in Na+-K+-Ca2+-Cl--SO42-/H2O subsystems were ...
-
(2004)The strength of lava crust and the role of that crust in determining lava flow dynamics and morphology are of fundamental importance in modeling lava flow behavior. Great improvements to flow models have been made by ...
-
(2001)Solutions are developed for the harmonic interior pressurization of idealized hemispherical lava domes to determine the evolution of instability with time. Integrated gas pressure distributions are evaluated to determine ...
-
(1995)Parallel studies conducted recently on the mechanism of adsorption of arsenate and selenate oxyanions on iron oxyhydroxides have resulted in different structural models. On the basis of EXAFS-derived As-Fe distances, ...
