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 ...

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.

Is the asthenosphere electrically anisotropic?
Earth and Planetary Science Letters, 2000Abstract Two techniques for resolving the conductance of an electrically conductive asthenosphere are presented. The first technique combines observatory electromagnetic data in the period range of the daily variation and longer, which provides penetration depths of 400 km and deeper, with laboratory data of the conductivity of upper mantle materials.

Melt squirt in the asthenosphere
Journal of Geophysical Research, 1975The interpretation of the seismic low-velocity zone as a region of partially molten rock is extended to explain the transient displacements following the 1946 Nankaido earthquake. Three partial melt models are considered to account for the observed time constant of 3–5 years: large-scale diffusion of melt through a porous matrix can decay over ...

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 ...

Geochemistry, Geophysics, Geosystems, 2016 A Global View of the Lithosphere-Asthenosphere Boundary
Science, 2009Seismic imaging reveals a global velocity anomaly at depths of 70 to 100 kilometers that may be from some melt or a strong fabric in Earth’s mantle.

Solubility considerations lead to a model of the asthenosphere which contains a CO2-rich liquid phase. The model explains variations in the asthenosphere between ocean and shield areas.
