On the Rifting Dynamics of Plate Divergence and Magma Accumulation at Oceanic Ridge Axes, transition layer. Both evolve simultaneously. A model is developed particularly for the situation in Iceland where a well studied rifting episode occurred in the Krafla volcanic system 1975–1984. Both the divergence and the buoyant rise of magma create tensile deviatoric stress in the axial region,

3-D Spherical Shell Modeling of Mantle Flow and Its Implication for Global Tectogenesis,luid medium to simulate mantle flow which fits the global tectogenesis quite well. The governing equations are derived in spherical coordinates. Both the thermal buoyancy force and the self-gravitation are taken into account. The velocity and pressure coupled with temperature are computed, using the

Oblique Subduction of a Newtonian Fluid Slab,ush force exerted along the trench, the slab pull force at the downdip of the slab, the gravitational body force within the slab, and the frictional resistance force at the upper surface of the slab. Because the slab motion along strike is being resisted by the frictional resistance at the interplat

On the Dynamics of Extensional Basin,ther in many respects. Surficial geological structures are characterized by a series of half-grabens with their one flank constituted by normal fault. Those extensional structures usually extend to a depth of 6–8 km. Therefore, the stress condition in the upper 8 km can be written as . where x, y de

Rheological Information from Geological Structures,o perturbations in flow that result in structures. Theory and modeling allow us to understand the conditions necessary for such structures to form and, conversely, we can use the form of the structures to infer possible rheological conditions for the rocks during natural deformation. We review here

A Method of Estimating the Stress Exponent in the Flow Law for Rocks Using Fold Shape,most other situations. The geometric characteristics of buckle folds in layered materials are dependent on rheological parameters, and in particular depend strongly on the stress exponent, .., of the stiff layers involved. Thus, information about the deformation rocks have undergone and their rheolo

Interrelation between Fault Zone Structures and Earthquake Processes,d relations between seismogenic structures and processes. In the present paper we search for the scale dependence in various earthquake phenomena with the hope to find some structures in the earth that may control the earthquake processes. Among these phenomena, we shall focus on (1) geologic struct

Analysis of Induced Seismicity for Stress Field Determination and Pore Pressure Mapping, numerous stress measurements have been conducted with the HTPF method. When inverted simultaneously, the HTPF data and the focal plane solutions help determine the complete stress field in a fairly large volume of rock (about 15 x 10.m.). These results demonstrate that hydraulically conductive faul
