(2003)Plate flexure is a phenomenon that describes how the lithosphere responds to long-term (>105 yr) geological loads. By comparing the flexure in the vicinity of ice, volcano, and sediment loads to predictions based on simple ...

LITHOSPHERIC STRESS FIELD AS A CONTROL OVER SEISMOGENIC FAULT PARAMETERS AND EARTHQUAKE MAGNITUDES (2001)Relations between the length of seismic rupture, amount of slip, and magnitude of earthquakes are investigated as a function of slip mechanism (normal, reverse, or strike slip) formed in different stress fields. The ...
-
(2003)A new mechanism for Paleozoic subsidence of the Russian, or East European, platform is suggested, since a model of lithosphere tilting during the Uralian subduction does not explain the post-Uralian sedimentation record. ...
-
(1999)Seismic attenuation (1/Q) changes abruptly between the stable Eurasian craton and adjacent mountain belts associated with the Alpine-Himalayan collision. New attenuation measurements on local body and coda waves provide ...
-
LITHOSTRATIGRAPHIC CHARACTERISTIC AND LITHOLOGY OF TRIASSIC-PALEOZOIC ROCKS OF SOUTHERN MANGYSHLAK (2004)The paper considers principles of the subdivision and correlation and a new petrographic model of Triassic–Paleozoic rocks based on their lithogenetic features. The structure of the folded basement and quasi-platform complex ...
-
(2002)Lower Paleozoic platform carbonate strata in northern Alaska (parts of the Arc-tic Alaska, York, and Seward terranes; herein called the North Alaska carbonate plat-form) and central Alaska (Farewell terrane) share distinctive ...
-
(1990)Liδ18OSiO2 relationships have been examined for suites of spilitized basaltic rocks (DSDP 504B; Xigaze Ophiolite; Blanco Fracture Zone; Greater Caucasus; Rhenohercynian Fold Belt) and intra-plate evolved tholeiites (Northern ...
-
(1995)The chemical and mineralogical compositions of Llanvirnian (Ordovician) iron and associated phosphate ooids from Sweden, Estonia and Russia have been examined. The oolites are generally thin and lean (mud supported), and ...
-
(1999)This paper presents the results of seismological observations carried out in the greater Sochi area using a network of self-contained seismic stations to record low-magnitude seismicity during the period November 1995 to ...
-
(2003)The sections existing in the Permo-Triassic effusive traps of the Siberian Platform (SP) are of three types: (1) monotonous, with slightly altered composition of tholeiites within several succesive formations in the same ...
-
(1999)Pyrope-grossular solid solutions, (Mg,Ca) 3 Al 2 Si 3 O 12 , of composition Py 85 Gr 25 and Py 75 Gr 25 were synthesized at 1000, 1200, and 1400 degrees C and 30 kbars in a piston-cylinder device. The synthetic garnets ...
-
(2000)Small scale structures produced by deformation and compaction are common in igneous, metamorphic, and sedimentary rocks, and are often used to define foliation and lineation directions. Analytic solutions for models of ...
-
(1998)At any set of thermodynamic conditions a mineral will have some well defined equilibrium crystal structure. However, this structure can be locally disturbed by crystal defects, such as domain walls or solute atoms. This ...
-
(2002)Trend analysis is widely used for detecting changes in hydrological data. Parametric methods for this employ pre-specified models and associated tests to assess significance, whereas non-parametric methods generally apply ...
-
(2002)The substitution in layered double hydroxide-like phases (LDH) of composition (Co2+1-y Cu2+y)2Al3+(OH)6Cl · n H2O (0 y 1) was studied by X-ray diffraction and X-ray absorption spectroscopy. It was found that the lamellar ...
-
(1989)The special features of this investigation are as follows: 1) we use readily accessible data; 2) the prediction is truly local, and the locations of the fields are determined within about 75 km; 3) the effectiveness of the ...
-
(1990)The prediction of petroleum and natural gas fields (especially very large ones) is a very interesting scientific problem and a highly important economic tasks. Other publications by the present writers using examples from ...
-
(2004)Pyrope-knorringite garnets, Mg3(Al1-X Cr3+X)2Si3O12 with X=0.25, 0.50, and 1.00, were synthesized between 9 and 16 GPa and 1300 and 1600 °C, using multianvil high-pressure techniques. The garnets with X=0.25 and 0.50 are ...
-
(1997)Stratigraphic investigations of the Precambrian in Karelia and the Kola Peninsula, which are the type area for the pre-Riphean part of the Proterozoic of northern Eurasia, demonstrate a priority of local stratigraphic ...
-
(2001)Recent seismological observations reveal the presence of seismic anisotropy in localized regions at the base of the mantle within an otherwise isotropic lower mantle. These regions can be placed in a tectonic context, ...
