-
(2001)We develop numerical simulations of basaltic lava flowing laminarly over a basalt substrate in order to examine the details of the lava dynamics and thermal boundary layers and to understand the implications for substrate ...
-
(2003)Dissolved oxygen concentrations in river-sediment porewaters are reported and modelled using a zero-order reaction rate and the Monod equation. After mixing the sediments and allowing settling, the dissolved oxygen profile ...
-
(1997)The paper sets out to determine the influence of various factors on the metal resources of hydrothermal systems in the ocean on the basis of a combined analysis of the results of an investigation of natural objects and ...
-
(2001)The characteristics and composition of particulate matter and water mass were determined within the Amur River estuary-Sea of the Okhotsk system during the summers of 1992 and 1993 using a variety of techniques including ...
-
(2001)The factors which control soil moisture patterns in a semiarid area are determined in two different locations: a burnt zone with little vegetation and an unburnt zone with a greater vegetal cover. In the burnt area, the ...
-
(1986)In the framework of plate tectonics, loci of trench-arc-backarc (T-A-BA) systems are identified with those of subduction, and various features characteristic to T-A-BA systems are causally attributed to subduction. While ...
-
(2003)The Earth may have been globally ice-covered several times during the Proterozoic. While the Neoproterozoic and the Paleoproterozoic glaciations may have been 'snowball' Earth events, there is no evidence for such glaciation ...
-
(1989)In certain sedimentary basin seismic exploration has revealed geological bodies consisting of layers that taper in one direction, sometimes to the point of pinching out. These layered structures occur widely along the ...
-
(2003)Fassaite is a major component of Ca-Al-rich inclusions (CAIs) of Types B and C that crystallized from liquids. In contrast, this mineral is rarely reported in Type A inclusions and has been much less studied. In this paper, ...
-
(2001)This work aims at investigating the processes leading to the liberation of CO2 and SO2/SO3 in the atmosphere after large meteorite impacts into sediments. Firstly, we review reactions and thermodynamic conditions to produce ...
-
(1998)Relaxation processes and present-day block structure were evaluated for a local area in the Lovozero Massif, proceeding from the fact that with a well-structured spatial distribution of relaxation sources one can treat ...
-
(2003)In this paper wavelet transforms and a logarithmic barrier method are applied to the inversion of large-scale magnetic data to recover a 3-D distribution of magnetic susceptibility. The fast wavelet transform is used, along ...
-
(2004)We address the problem of building an efficient algorithm for ray-based migration/inversion in complex media characterized by multivalued traveltime. Since the multivalued ray maps can be computed by wavefront construction, ...
-
(2002)Ferro-manganese nodules of the western Baltic Sea reveal enhanced heavy metal concentrations since the end of the 19th century and are therefore potentially useful for retrospective monitoring of the heavy metal pollution ...
-
(2001)Soil phosphorus (P) dynamics are controlled by the interaction of geochemical, biochemical and biological processes. Changes in species composition or management could alter the relative importance of these processes. We ...
-
(2003)A model of a ductile fault zone is incorporated into a forward 3-D earthquake model to better constrain fault-zone hydraulics. The conceptual framework of the model fault zone was chosen such that two distinct parts are ...
-
(2004)Damage zones showvery similar geometries across awide range of scales and fault types, including strike-slip, normal and thrust faults.We use a geometric classification of damage zones into tip-, wall-,and linking-damage ...
-
(2000)We study the initiation of slip instabilities of a finite fault in a homogeneous linear elastic space. We consider the antiplane unstable shearing under a slip-dependent friction law with a constant weakening rate. We ...
-
(2001)Using time sequence analyses of extensional fault models we demonstrate the pivotal role played by fault segmentation in the accumulation of displacement and length during the growth of faults. Experiments are described ...
-
(2000)Faults usually are not isolated features but exist within a population of faults which may interact through their stress fields. This poses two serious problems for seismic hazard analysis. The most severe such problem ...
