The seismic low-velocity zone (LVZ) of the upper mantle is generally associated with a low-viscosity asthenosphere that has a key role in decoupling tectonic plates from the mantle. However, the origin of the LVZ remains unclear. Some studies attribute its low seismic velocities to a small ...
The first question applies to the conventional rigid plate hypothesis Turcotte and Schubert, 1982, Morgan, 1998, as restated in a recent review (Kearey and Vine, 1990, p. 73): “Within the basic theory of plate tectonics, plates are considered to be internally rigid, and MORB recycling, ...
The time series from widely separated regions show strong correlations with one another and it is suggested that tectonic plates are subjected to a fluctuating stress field that results in these changes in seismic activity.doi:10.1038/258490a0Chinnery, Michael A....

Newer crustal rocks have also been found in the ocean floor along ridges where plates are slowly separating, which offers more evidence for the plate tectonic theory. Crustal Rock Age Mapping and studies of the ocean floor provides further plate tectonic theory evidence such as the presence of ...
Lithosphere rheology is a key parameter to understand the dynamics of continental subduction following the closure of paleo-oceans during convergence between tectonic plates. Serpentinites are commonly inferred in many subduction zones1,2,3. They are the principal water carrier toward the mantle, with ...

Overlapping subduction of the Pacific and Philippines Sea plates leads to an enhanced fluid flux to the mantle source of arc volcanoes in central Japan. Spatial variability in the amount of fluid that each plate contributes is determined by the configura
