(1989)The paper discusses data that support the view that the Sea of Okhotsk region is a dynamic geosynclinal region. However, at least in the southern part of the region, the geosynclinal process involved only the emplacement ...
-
(2004)The paper deals with the problem of electromagnetic pulses, which are generated in the earthquake centre at the very moment of main shock, and the co-seismic magnetic oscillations accompanying the propagation of the Love ...
-
(1989)The author investigates vertical motions of the lithosphere (L) resulting from a complicated injection of melt from the underlying asthenosphere. The kinematics of the process is illustrated. The complete system of equations ...
-
(2004)The possibility of flow of the lower crust under the load produced by carbonate sedimentary accumulations is investigated through the example of the Paris basin during the Middle Jurassic (i.e. Bathonian). Depositional ...
-
(2002)The theory of the proton magnetic resonance sounding (a.k.a. surface nuclear magnetic resonance) was first developed in free space. In this case, the alternative excitation field has no phase variation. Hence there is no ...
-
(2004)Existing models for seismic wave velocity dispersion and attenuation in porous rocks containing a mixture of two pore fluids are based on the assumption of a regular distribution of the fluid phases. However, in reality ...
-
(2001)This paper investigates the ability to retrieve the true soil moisture and temperature profiles by assimilating near-surface soil moisture and surface temperature data into a soil moisture and heat transfer model. The ...
-
(2000)Cetyltrimethylammonium-and tetradecyltrimethylammonium-intercalated magadiites were prepared by direct syntheses, starting from sodium metasilieate (NaaO/SiO2 = 1.0) and nitric acid. Total substitution of sodium by ...
-
(2002)During the last three billion years, the Earth has been experiencing a slow global cooling, expressed in the progressively increasing frequency and scale of glacial events. Based on these indications, geologic history can ...
-
(1991)An examination was made of the nomenclature, distribution, petrogeochemical characteristics and relationship with mineralisation of dyke rocks with an exotic rare-metal composition - ongonites (sodium branch) and elvanites ...
-
(2001)The rapid depressurisation and discharge of volatile rich silicic magma chamber and the onset of caldera collapse associated with ignimbrite eruption is investigated using combined theoretical and experimental approaches. ...
-
ONSET OF CONNECTIONS BETWEEN THE PACIFIC AND ARCTIC OCEANS THROUGH THE BERING STRAIT IN THE NEOGENE (2004)New data on the Neogene diatoms, mollusks, and magnetostratigraphy in the North Pacific and surrounding structures suggest the Bering Strait incipient opening in the latest Miocene or probably in the earliest Pliocene. ...
-
(2003)Low summer insolation would increase Northern Hemisphere ice sheets only if winter snow persisted all year. Lake Baikal records reveal that such a climatic threshold may have been reached at around 4.0 Ma. Insolation minima ...
-
ONSET OF SUBDUCTION AS THE CAUSE OF RAPID PLIOCENE-QUATERNARY SUBSIDENCE IN THE SOUTH CASPIAN BASIN (2002)Backstripping a representative stratigraphic column from the northwest of the South Caspian basin shows that 2.4 km of tectonic subsidence has occurred since ca. 5.5 Ma, at 1.5–10 times the rate recorded in typical foreland ...
-
(2001)Ontogenetic trends (umbo to growth edge of shell) in aspartic acid (Asp) racemization and amino acid composition and their evolution over time are examined in serial samples of annual growth bands from a time-series of ...
-
(2001)The chemistry and mineralogy of a group of opaque mineral assemblages in the matrix of the Bishunpur LL3.1 ordinary chondrite provide insight into the nebular environment in which they formed. The assemblages consist of a ...
-
(2002)Vent processes were examined at Karymsky volcano, Kamchatka, by measuring SO2 emissions using a correlation spectrometer (COSPEC). Continuous high-sensitivity COSPEC measurements and physical observations were collected ...
-
(2000)It is commonly assumed that an olivine-hosted melt inclusion is chemically isolated from the melt surrounding its host crystal. This assumption is probably valid for slow-diffusing, incompatible trace elements, but for ...
-
(2004)Significant petrogenetic processes governing the geochemical evolution of magma bodies include magma <unl>R</unl>echarge (including formation of ‘quenched inclusions’ or enclaves), heating and concomitant partial melting ...
