Moving lithospheric plates and mantle convection

open access: yesGeophysical Journal International, 1979
Summary. The coupling between a rigidly moving lithospheric plate and a convecting mantle is investigated using a simple two-dimensional numerical model that incorporates a horizontally moving upper boundary, simulating the effect of a moving plate, over a fluid layer heated from below.

A story of lithospheric plates

The Project Repository Journal
A story of lithospheric plates Whether plate tectonics began 850 million years ago or earlier is uncertain. FINGER-PT hypothesises that preservation bias obscures evidence of earlier modern-like tectonics. To test this, the project analyses detrital minerals in sedimentary rocks, employing experimental petrology, elastic barometry, and

Lithospheric Plates, Benioff Zones, and Volcanoes

Geological Society of America Bulletin, 1971
Earthquake focus depth contours delineate undulating surfaces which may represent the tops and bottoms of lithospheric plates 50 to 75 km thick, dipping beneath island arcs. The same data can be contoured as a single surface only with difficulty and with anomalous points. Active volcanoes lie above axes of undulations which plunge down the slope of the

On the forces not moving lithospheric plates

Tectonophysics, 1974
Abstract Plume tectonics is examined as an alternative to thermal convection as a mechanism of continental drift and plate movements. The concept of plumes seems difficult to reconcile with the principles of mechanics.

Size distribution of the number of lithospheric plates

Izvestiya, Physics of the Solid Earth, 2008
To describe the cumulative distribution of the number of lithospheric plates over areas S, the dependence N(≥S) ∼ S−0.33 was proposed by Bird [2003]. Based on dimension considerations, the dependence N(≥S) ∼ (ɛ/S)1/3, where ɛ is the generation rate of kinetic energy of convection in the mantle estimated at 10−11 m2/s3, is proposed. The analogy of plate

Dips of Downgoing Lithospheric Plates Beneath Island Arcs

Geological Society of America Bulletin, 1970
Dips of downgoing lithospheric plates were measured by inspecting published vertical sections of relocated hypocenters beneath Pacific and Indian island arcs. For any one arc the maximum dip of the slab in a particular section, as determined by the hypocenter configuration, is inversely proportional to the distance from the section to the pole of ...

Terrestrial impact craters track the voyage of lithospheric plates

Geological Journal, 2022
The paradigm of plate tectonics has aided in the identification of the journey of continents on the globe, their assembly into supercontinents, disruption, and re‐assembly.
