Plate Tectonics

Introduction

Plate tectonics, our basic paradigms, as excavation work, was created in 1960 after decades of observational studies, which culminated in the key discoveries, such as geomagnetic roll, mid-ocean ridges, the conversion errors, and seafloor spreading, together, these ideas have led to 'new global tectonics "or the theory of plate tectonics (Jacoby Bergeron Malvesy 1996). Movement of the plate relative to each other and the mantle have been the subject of numerous studies. The history of the relative motion of the plate is derived from the mapping of marine magnetic anomalies and morphology of the seabed using the implementation of Euler's theorem for rotations at area. Problems and solutions

Procedures for determining the optimum parameters of the rotation of the plate was developed in 1980, when the criterion for the installation of conjugate functions has been established and it became clear that the uncertainty in plate rotations are best expressed in a small perturbation to the optimal rotation. Using improved observation of morphology bottom, derived from multibeam bathymetry and satellite gravity, combined with better coverage of magnetic anomalies have allowed researchers to improve the resolution model of the relative motion of the plate, deviations from first-order approximation of a rigid plate. Such deviations are now regularly treated as diffuse plate boundaries (Jacoby Bergeron Malvesy 1996).

The absolute motion of the plate is usually denoted motion relative to a fixed mantle, and the most prominent point of the mantle has been proposed fixed hot spot reference frame. This reference comes from the geometry of the hot islands, and seamounts on the network. Distribution of seamounts was used to assess the origin of volcanism in the plate, and it seems clear that the distribution is made up of contributions from small seamounts produced in the immediate environment on the ridge, more to do with seamounts island arcs, as well as a number of dimensions associated with numerous hot points.

Plate tectonics is largely controlled by buoyancy distribution of oceanic lithosphere, which correlates well with lithospheric age. Buoyancy also depends on the composite layers as a result of the pressure relief of partial melting under mid-ocean ridges, and this process is sensitive to pressure and temperature conditions, which vary strongly from the terrestrial planets, as well as during cooling of secular history of the planets. In the experiments, simulation studies, they filed a range of values for the acceleration of gravity ...
