Viscosity Distribution within the Earth

There are three sets of data ( L = wavelength, t r = relaxation time) by using which we can determine the viscosity distribution within the Earth. They are the Fennoscandian uplift, Earth oblateness and a Pleistocene lake uplift. It is shown in the present paper that these are compatible only with a...

Description
Summary:There are three sets of data ( L = wavelength, t r = relaxation time) by using which we can determine the viscosity distribution within the Earth. They are the Fennoscandian uplift, Earth oblateness and a Pleistocene lake uplift. It is shown in the present paper that these are compatible only with a thin viscous channel in the upper mantle. The result seems to preclude lower mantle convection.
