Lithospheric Deformation and Asthenospheric Pressure

1990
We present here a model of lithospheric deformation caused by a radial pressure acting at the base of the lithosphere. Such a pressure may arise, for instance, as a result of convective motions occurring in the Earth’s mande. As a first approximation, we consider a rather simple Earth model consisting of a fluid interior, the mantle or asthenosphere ...

Geodynamics of melting in the Asthenosphere

2016
At geological time-scales, the mantle behaves as a high Rayleigh number fluid, i.e., thermal convection takes place and produces cells circulating at variable sizes and speeds. A lot of effort has been made to understand the upwelling part of these cells occurring underneath ridges and hotspots where they give birth to volcanoes.

Three‐dimensional seismic inhomogeneities in the lithosphere and asthenosphere: Evidence for decoupling in the lithosphere and flow in the asthenosphere

Reviews of Geophysics, 1982
Newly discovered three‐dimensional seismic velocity anomalies in the earth's lithosphere and asthenosphere are interpreted in terms of decoupling in the lithosphere and flow in the asthenosphere. A rough estimate of flow in the asthenosphere under California was made using Stokes' law on the basis of the size of anomalies and density contrast estimated
