On the Origin of the Asthenosphere
Earth and Planetary Science Letters, 2012Abstract Various models of the origin of the asthenosphere are reviewed based on the latest observations on mineral physics of mechanical properties, melting relationships and the thermal models of the upper mantle. Partial melting likely occurs throughout the upper mantle except for the lithosphere.

Plug Flow in the Earth's Asthenosphere
Earth and Planetary Science Letters, 2018 Abstract Recent seismic observations, focused on mantle flow below the Pacific plate, indicate the presence of two shear layers in the Earth's asthenosphere. This is difficult to explain under the classic assumption of asthenosphere flow driven by plate shear from above.

Izvestiya, Physics of the Solid Earth, 2011
Based on the analysis of the thermal history of the mantle, we hypothesize the existence of the partially molten layer at a depth of approximately 700–1100 km under the entire Earth's surface. We present the seismological data that are consistent with this hypothesis and the geoelectric results revealing the conductive layer at similar depths in ...

Lithosphere–Asthenosphere Viscosity Contrast and Decoupling
Physics of the Earth and Planetary Interiors, 2011The coupling/decoupling between the lithosphere and asthenosphere has significant implications for understanding many important aspects of plate tectonics and geodynamics. To drive plate motion, man- tle convection requires coupling at the lithosphere–asthenosphere (LA) interface.

The Lithosphere-Asthenosphere Boundary
Annual Review of Earth and Planetary Sciences, 2010Seismological models of upper-mantle structure are providing new constraints on the physical and chemical properties that differentiate the lithosphere from the asthenosphere. A wide variety of studies are consistent with an oceanic lithosphere that corresponds to a dry, chemically depleted layer over a hydrated, fertile asthenosphere.

Geological Society of America Bulletin, 1946
From the geophysical and physical laboratories at Harvard University have recently come data bearing on the effect of rising temperature on the compressibility of liquids, glasses, and crystalline solids. These new data have compelled the author of the following article to revise an earth-model which, in 1942, he derived from some general assumptions ...
