(2002)We present a numerical approach, based on a spectral analysis, for the initiation of the unstable slip on a finite fault region. First we focus on one fault model. We study the relationship between the weakening parameter ...
-
(1989)New data on the solubilities of noble gases in basaltic melts and on their distribution between melt and restite, together with the idea that outgassing of the mantle results from the generation of oceanic lithosphere, the ...
-
(2002)Numerical modeling on a geological timescale is a rapidly expanding tool to investigate controls on formation of the stratigraphic record. Modeling enables us to test existing ideas, but verification of model results is ...
-
(1999)The surface charge of magnesite (MgCO3) was measured at 25°C as a function of pH (4.6 to 11) and ionic strength (0.01, 0.1 and 0.5 M NaCl) under pCO2 from 10-3.5 to 0.96 atm. The acid-base titrations were performed in a ...
-
(1999)Steady-state dissolution rates of magnesite (MgCO3) were measured at 25°C as a function of pH (from 0.2 to 12), total dissolved carbonate concentration (10-5 < ΣCO2 < 0.1 M), and ionic strength (0.002 < I < 0.5 M) using a ...
-
(1999)The 18O/16O ratio of soil CO2 is important for both global and ecosystem scale budgets of the 18O/16O ratio of atmospheric CO2, as well as for using this ratio as a proxy for the isotopic ratio of soil water. The 18O/16O ...
-
(1999)The southern Ural Mountains of Russia contain a well-preserved, well-exposed Paleozoic accretionary wedge and forearc that can be readily compared to those in active arc-continent collision zones. The early convergent ...
-
(2002)We discuss the structure of the continental lithosphere, its physical properties, and the mechanisms that formed and modified it since the early Archean. The structure of the upper mantle and the crust is derived primarily ...
-
(2000)LaCrO3 thin films were successfully prepared at lower temperatures by the sol-gel process based on organic chelating precursors. The formation and transition of the gel derived from the chelate solution were analyzed by ...
-
(1998)Theoretical relations were derived for the time of geomagnetic precursors as a function of epicentral distance and earthquake magnitude. Theoretical curves fit observation data fairly well.
-
(2003)At present, mainly kinematic records are processed by wave refraction method [2, 3]. Usually, refracting boundaries and velocities (boundary, stratal, and average) are shown on the seismic profiles. Dynamic peculiarities ...
-
(2002)We have determined the production yields for radionuclides in Al2O3, SiO2, S, Ar, K2SO4, CaCO3, Fe, Ni and Cu targets, which were irradiated with slow negative muons at the Paul Scherrer Institute in Villigen (Switzerland). ...
-
(2003)We study how the production rates of cosmogenic nuclides in solid targets at the Earth's surface depend on the shape and size of a sampled rock and the position of a sample. We use a physical model simulating the interaction ...
-
(2003)The anthropogenic production of greenhouse gases and their consequent effects on global climate have garnered international attention for years. A remaining challenge facing scientists is to unambiguously quantify both ...
-
(2002)The laboratory analyses of cosmic dust analogues—that in the context of this paper include interstellar, circumstellar as well as cometary dust—have a critical role in the study of circumstellar and cometary dust. The ...
-
(2002)Noble gases within the crust originate from three main sources: the atmosphere, introduced into the crust dissolved in groundwater; the mantle, in regions of magmatic activity; and those produced in the crust by the result ...
-
(1997)This work aims to highlight the relationship between primary productivity, sulphate reduction and organic carbon preservation in cyclic marine sediments from the Kimmeridge Clay Formation. A concomitant increase of the ...
-
(1999)Stress during volcanic crises is high, and any friction between scientists can distract seriously from both humanitarian and scientific effort. Friction can arise, for example, if team members do not share all of their ...
-
(1996)Cross sections of two Mercenaria mercenaria shells, one modern and one Pleistocene, and one modern Spisula solidissima shell were analyzed for trace metals using laser ablation-inductively coupled plasma-mass spectrometry ...
