Abstract
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, overlain by an elastic lithosphere. The model as a whole is assumed to be incompressible and have a constant mass density throughout. These simplifying assumptions allow us to find analytical solutions to the equations of gravito-elasticity which we use here in a peculiar way. We believe that these solutions provide a sufficiently meaningful description of the global yield of the actual terrestrial lithosphere, and thus may be used to model the evolving shape of the lithosphere.
