SEDIMENTATION OF MONODISPERSE SILICA SPHERES AND THEIR COAGULATION AGGREGATION AT HIGH TEMPERATURES (2004)The effect of high temperatures on the sedimentation of suspensions of monodisperse silica spheres (MSS) is considered. The MSS suspensions chosen as a model for our research, with ethanol as a dispersion medium, are stable ...
-
(2000)With this paper we present a first attempt to combine the direct results on lithology, composition and age dating in the boreholes BDP-93, BDP-96 and BDP-97 with geological and seismic data from the areas where those ...
-
(1996)In recently formed marine barite (BaSO4) separated from two equatorial Pacific cores 226Ra activity exceeds that of its parent 230Th by at least an order of magnitude, indicating radium uptake during barite precipitation. ...
-
(2001)A modelling exercise was undertaken to evaluate the positive (preservational) and negative (diluent) effects of sedimentation rate (SR) on the total organic carbon (TOC) content of marine sediments, and to use multiple ...
-
(1987)The authors analyzed the variability of rates of manganese-nobule growth and rates of sedimentation in abyssal areas of ocean on the basis of published information, as well as our own data. Growth rates of manganese nodules ...
-
(2006)The sediment composition and sedimentation conditions of Maastrichtian and Danian deposits in the vast territory of the Russian plate and adjacent regions of North Eurasia were studied. The succession of Late Cretaceous ...
-
(2003)"Oceanic Anoxic Event" on the boundary of Cenomanian-Turonian (OAE2) is a bright episode in Cretaceous history. Results of the sedimentological and palynological researches of Cenomanian-Turonian of terrigenous deposits ...
-
(2002)The paper gives a comprehensive survey of the materials on sedimentation in the lakes of Leningrad region. On the strength of the new data on the structure of bottom sediments the authors conclude that sedimentation ...

SEGMENT LINKAGE DURING EVOLUTION OF INTRACONTINENTAL RIFT SYSTEMS: INSIGHTS FROM ANALOGUE MODELLING (2003)On the basis of the effective scale-independence of brittle structures, from microcracks to regional fault systems, we have used analogue centrifuge models to provide insights into the initiation and evolution of continental ...
-
(1998)Low ionic strength waters containing significant calcium and bicarbonate are common in nature, but little literature exists on their behaviour during freezing. Modelling indicates that freezing-induced concentration of ...
-
(2000)Vesicle cylinders represent a spectacular kind of segregation structure involving residual liquids formed in situ during the cooling of lava flows. These vertical pipes, commonly found within basalt flows typically 2-10 m ...
-
(2003)A small swarm of 80 earthquakes was observed beneath Koryakski volcano between March 1 and May 31, 1994. These earthquakes ranged from 0 to 8 km in depth and from −2.0 to 1.5 in magnitude (ML). The swarm under Koryakski ...
-
(2002)Paleoseismologic studies of recent years on the southern slope of the Northwest Caucasus show major earthquakes of up to M 7.0 to have occurred in the past in the number of geologically active fault zones. Recurrence ...
-
(2002)Seismic anisotropy provides evidence for the physical state and tectonic evolution of the lithosphere. We discuss the origin of anisotropy at various depths, and relate it to tectonic stress, geotherms and theology. The ...
-
(1996)Seismic anisotropy beneath continents is analyzed from shear-wave splitting recorded at more than 300 continental seismic stations. Anisotropy is found to be a ubiquitous property that is due to mantle deformation from ...
-
(2004)Analytical expressions for three P-wave attenuation mechanisms in sedimentary rocks are given a unified theoretical framework. Two of the models concern wave-induced flow due to heterogeneity in the elastic moduli at ...
-
(2001)The coherent-state transform (CST) is essentially a Gaussian-windowed Fourier transform and it yields a combined slowness-position (p, x) domain representation of seismic wavefields. Several forms of the inverse CST exist ...
-
(1989)Traditional instrumental seismologic observations provide information on the accelerations, velocities and displacements of the ground at various distances from the centers of earthquakes and explosions. Seismic instruments ...
-
(1989)The southern, deep-water part of the Aegean Sea includes the Cretan Trough, which is bounded in the north by the South Aegean volcanic belt (with the well known Santorin volcano) and in the south by the Hellenic Island Arc ...
