-
(1992)New multichannel seismic-reflection profiles shot across the north Ural thrust front indicate the presence of previously unknown wedge-shaped foreland-verging blind duplex. The structure of this zone shows westward thrusting ...
-
(2005)The paper presents examples illustrating the current blind predictive capabilities of the diffuse double layer model (DDLM) as the model requiring the smallest set of parameters and thus being most suitable for substituting ...
-
(1988)As our input information in the study of the West Siberian Plate, we use data from magnetic and gravimetric sounding and seismic exploration by the combined refracted-wave technique and the common depth point technique. ...
-
(1989)We wish to determine the causes of the spatial and temporal hierarchical properties of the block structure of the geophysical medium. In the present paper we suggest an interpretation of this phenomenon. We know from general ...
-
(2002)One of the principal objections to the logratio approach for the statistical analysis of compositional data has been the absence of unbiasedness and minimum variance properties of some estimators: they seem not to be BLU ...
-
(2003)Amphiboles were hydrothermally synthesized at 500 8C and 4 kbar in the system Li2O-Na2O-FeO- Fe2O3-SiO2-H2O, with nominal compositions along the riebeckite [¦ Na2Fe3 2+ Fe2 3+ Si8O22(OH)2]-ferri-clinoferroholmquistite [¦ ...
-
(2002)The Chixculub impact occurred at the Cretaceous/Tertiary (K/T) boundary, and although several other Late Cretaceous and Paleogene impact craters have, at times, been linked with the K/T boundary, isotope geochronology has ...
-
(2004)Bond-valence methods for the prediction of (hydr)oxide solution monomer and surface functional group acidity constants are examined in light of molecular structures calculated using ab initio methods. A new method is ...
-
(2000)The bonding and dynamics of Mg in pyrope are investigated using density functional theory calculations. The potential which the Mg experiences is highly anisotropic and in one direction is strongly anharmonic. Frequencies ...
-
(2002)The charge density and bond character of the rutile-type structure of SiO2 (stishovite) under compression to 30 GPa were investigated by X-ray diffraction study using synchrotron radiation and AgKα rotating anode X-ray ...
-
(1999)The Si L 2,3 core-loss edge can be used to probe the crystal chemistry around Si, providing information on the s-and d-like partial density of unoccupied states of the Si-O bonds. We present Si L 2,3 edges from 59 silicates, ...
-
(2002)We combined synchrotron-based X-ray absorption near edge structure (XANES) spectroscopy, extended X-ray absorption fine structure (EXAFS) spectroscopy and binding affinity studies to determine the coordination, geometry, ...
-
(2003)The fraction of O atoms as non-bridging O atoms (NBO) can be well approximated based on composition alone in many silicate glasses, but the NBO preference for specific network forming cations is much less well known. Using ...
-
(1987)Dredging on the island slope of the Izu Trench brought up volcanic rocks of the marianite-boninite series among fragments of the ophiolite complex. One distinguishing feature of these marianite-boninite rocks is the presence ...
-
(1997)Spatial correlations of principal Late Paleozoic biochores usually referred to as boreal and tropical communities are discussed. The distribution of corresponding geographic ranges is shown to be inconsistent with the ...
-
(1999)Deposits and boreal marine fossils of the Upper Bathonian are discovered in the Volga River middle courses, the central Russian plain. The deposits occur below the elatmae Zone considered as the East European equivalent ...
-
(1997)We offer a boreal zonal standard scale providing an effective panboreal correlation and current geological dating of Mesozoic boreal sediments. The need for establishment of a boreal standard is brought about by the fact ...
-
(2003)Mollusk migrations of various intensity in the Kimmeridgian to Valanginian time span were established in the Boreal Atlantic (West and East European Provinces), Boreal Pacific (Chukotka-Canadian and Boreal Pacific Provinces), ...
-
(2004)High-resolution flowmeter measurements such as those obtained with heat-pulse and electromagnetic flowmeters are often analyzed to produce in situ permeability profiles of heterogeneous aquifers. However, the borehole ...
-
(2004)This paper concerns the interpretation of borehole geophysical data from basalt sequences, especially continental basalt sequences that host aquifers. Based on modifications of the rules used for interpreting borehole data ...
