(2002)Fluxes of particulate organic carbon (POC) through the oxygen deficient waters in the eastern tropical North Pacific were found to be relatively less attenuated with depth than elsewhere in the eastern North Pacific. The ...
-
(2004)The paper presents an overview of the scientific research carried out in the frames of Working Group 1 activities of the COST Action 271. The basic objective of this Working Group was the study of the impact of ionospheric ...
-
(1996)Asteroids and comets that are vaporized during hypervelocity impact events can inject large masses of S into the stratosphere where it can potentially affect the radiation budget of the Earth, alter the chemistry of the ...
-
(2003)Many papers on meteorite impact suggest that large impacts can induce volcanic eruptions through decompression melting of the underlying rocks. We perform numerical simulations of the impact of an asteroid with a diameter ...
-
(1995)Imperfections in the perfect fractional melting (PFM) process can ameliorate the drastic “stripping” of incompatible trace elements from the residue which characterises ideal PFM, and the consequent catastrophic collapse ...
-
(1993)Noble gases were extracted in steps from grain size fractions of microdiamonds (less than 100 microns) from the Kokchetav Massif, Northern Kazakhstan, by pyrolysis and combustion. The concentration of He-4 in the diamonds ...
-
(2003)This paper investigates whether a micromechanical model developed to investigate the relation between the basic failure processes at grain-scale and the macroscopic failure pattern can be applied to model the fracturing ...
-
(2003)We analyse the effect of uneven ray coverage in global surface wave tomography. An inhomogeneous distribution of seismic rays may bias tomographic models because certain areas are better sampled than others. It is possible ...
-
(1997)Experimental partitioning of platinum-group elements (PGE) Os, Ir, Ru, Pt, and Pd, and Au between (Fe, Ni)-sulfide liquid and basaltic melt have been carried out at high Ni content with 67 ± 1 mol% NiS and 50 to 400 ppm ...
-
(2004)Based on elementary molecular-chemical concepts, one can trace the evolution of the gaseous phase of an endogenic fluid at its temperature equilibrium with host rocks. As can be seen, the final result of this evolution ...
-
(2001)Observations from deep boreholes at several locations worldwide indicate that (i) hydrostatic pore pressures persist to depths of as much as 12km in the upper crust, (ii) the brittle crust is in a state of failure equilibrium ...
-
(1990)We discuss the geological, geophysical, and petrological observations that constrain the nature of mantle convection in plumes, and show how theoretical models of mantle plumes have developed over the past three decades. ...
-
(2002)The Nb/U and Th/U of the primitive mantle are 34 and 4.04 respectively, which compare with 9.7 and 3.96 for the continental crust. Extraction of continental crust from the mantle therefore has a profound influence on its ...
-
(2001)Large permeability anisotropy due to anisotropic alignment of clay shape fabric may play an important role in focusing fluid flow along fault zones in clay rich rocks. The degree of permeability anisotropy depends on the ...
-
(2002)Strong scattered arrivals are observed in the 800-1400-km offset range of the four Peaceful Nuclear Explosion (PNE) seismic sections along the 3500-km-long E-W-trending Russian profile Kraton. They give evidence of an ...
-
(2006)Various scenarios of earthquakes and the associated tsunami wave generation are numerically simulated. It is shown that, depending on the chosen dynamic source parameters in the central seismic gap zone of the Kurile-Kamchatka ...
-
IMPLICATIONS OF THE TEMPORAL DISTRIBUTION OF HIGH-MG MAGMAS FOR MANTLE PLUME VOLCANISM THROUGH TIME (2002)We compile a 3.7-b.yr.-long time series of ultramafic and mafic rocks including extrusives and shallow intrusives (dikes and sills). We infer that peaks in the time series represent mantle plume events. Rocks erupted from ...
-
(2004)In basin modeling the thermodynamics of a multicomponent multiphase fluid flux are computationally too expensive when derived from a cubic equation of state and the Gibbs equality constraints. In this article we present ...
-
(2002)Planetary geology provides information on processes on the surface and interiorl of terrestria planets, satellites, and asteroids in the solar system. Surface composition and mineralogy is one of clues to understand planetary ...
