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 ...

Fluid Dynamics Research, 2008
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

Inferring blocked mantle convection
Science, 2019Geophysics The boundaries between rocks with different physical properties in Earth's interior come from either a change in crystal structure or a change in chemical composition. Wu et al. examined the roughness of the boundary between Earth's upper and lower mantle, thought to form from a change in mineral structure (see the Perspective by Houser). To

Geochemical Reservoirs and Whole-Mantle Convection
Mineralogical Magazine, 1998There are currently four rather separate approaches to study the evolution and present state of mantle dynamics, (1) geochemical characterization of mantle reservoirs by studying isotopes and trace elements in mantle rocks and mantle-derived melts, (2) high-pressure mineralogy, (3) numerical simulation of mantle convection, and (4) seismic tomography ...

Lagging mantle convection, the geoid and mantle structure
Earth and Planetary Science Letters, 1984Abstract In numerical models of convection incorporating migration of a simulated subduction zone, the main descending flow lags far behind the migrating trench, and a geoid low is associated with the main descending flow. This provides physical plausibility for the suggestion by Chase and Sprowl that present very long-wavelength (degree 2–4) geoid ...
