Mantle convection beneath East Asia under global mantle convection spherical framework
2020<p>East Asia is a tectonically active area on earth and has a complicated lithospheric deformation due to the western Indo-Asian continental collision and the eastern oceanic subduction mainly from Pacific plate. Till now, mantle dynamics beneath this area is not well understood due to its complex mantle structure, especially in ...

Mantle Convection and Viscoelasticity
Annual Review of Fluid Mechanics, 1985The ongoing revolution in the Earth sciences, which began more than twenty years ago, was originally based upon the increasingly widespread acceptance of the idea that continental masses have moved horizontally with respect to one another throughout geological time.

The term thermal convection implies a flow dri"ven by thermal density variations, these variations being in turn maintained against the action of diffusion by the advection of heat by the flow itself. The energetics is a balance between viscous dissipation and the release of potential energy by the rising and sinking of warm and cold material ...

An infinite Prandtl number, anelastic axially symmetric mantle convection model which incorporates the effects of both the exothermic 410 km and endothermic 660 km phase transitions that exist in the mantle of the earth is employed to study the effects these phase transitions have on the mantle flow.

This chapter presents the fundamental physics necessary to understand the complex fluid dynamics of mantle convection. The first section derives the equations of conservation for mass, momentum, and energy and the boundary and interface conditions for the various physical quantities.

Numerical Models of Mantle Convection
Annual Review of Fluid Mechanics, 1992An overview of numerical methods describing the structure and dynamics of the mantle is presented with attention given to novel 3D modeling techniques. The paper reviews 3D spherical and Cartesian models for constant viscosity emphasizing the assumptions regarding style of convection, time dependence, and implications for the mantle.

Mantle convection for geologists
Choice Reviews Online, 2011Mantle convection is the fundamental agent driving many of the geological features observed at the Earth's surface, including plate tectonics and plume volcanism. Yet many Earth scientists have an incomplete understanding of the process. This book describes the physics and fluid dynamics of mantle convection, explaining what it is, how it works, and ...

Convection in planetary mantles
Icarus, 1968Abstract In the present paper we consider a self-gravitating sphere, of radius R and of uniform density, consisting of a core extending to a fraction η of the radius of the sphere and with a viscous mantle overlying the core. In the mantle departures from the state of equilibrium have given rise to internal motions, which are time-independent and ...

The solid-state convection in the Earth mantle is characterized by plate tectonics, which shapes the tectonic activities of the Earth, and superplumes as broad hot regions chemically distinct from the surrounding regions in deep lower mantle. Recent numerical studies of mantle convection suggest that the rigidly moving plates occur on the Earth because
