A continuous kinematic model of plate-tectonic motions

A continuous kinematic model of plate-tectonic motions

S U M M A R Y One of the many problems in the study of plate-mantle coupling is the disparity between the theory of mantle dynamics-which involves continuum physics-and the theory of plate tectonics-which employs discontinuous plates. This discordance causes a variety of difficulties in geodynamic models, e.g. infinite tractions between the plates and mantle. As motions of the Earth’s surface d...

Pre - Plate - Tectonic

Geological models of subduction zones impact thinking about many of the central problems in the structure, dynamics, chemistry, and history of the solid earth. Should those models change, the effects will reach across the earth sciences. We are currently in the midst of such a change, brought on by several causes. First, the earth science community recently began an organized, multi-disciplinar...

The Thermogeographic Model in Paleogeography: Application of an Abiotic Model to a Plate Tectonic World

Plate tectonic reconstructions with continuously closing plates

We present a new algorithm for modeling a self-consistent set of global plate polygons. Each plate polygon is composed of a finite list of plate margins, all with different Euler poles. We introduce a "Continuously Closed Plate" (CCP), such that, as each margin moves independently, the plate polygon remains closed geometrically as a function of time. This method solves emerging needs in computa...

Tectonic plate under a localized boundary stress: fitting of a zero-range solvable model

We suggest a method of fitting of a zero-range model of a tectonic plate under a boundary stress on the basis of comparison of the theoretical formulae for the corresponding eigenfunctions/eigenvalues with the results extraction under monitoring, in the remote zone, of non-random (regular) oscillations of the Earth with periods 0.2-6 hours, on the background seismic process, in case of low seis...
