• W1569882864 abstract "We present here a new test of the layered convection hypothesis based on mantle-flow calculations which employ three-dimensional seismic models of mantle structure. The mantle-flow predictions are obtained using a newly reformulated viscous flow theory which also incorporates the constraints arising from the observed geometry of rigid surface plates. The motions of the tectonic plates are predicted, rather than imposed. We derive, through a formal inversion procedure, the mantle viscosity profile that provides a best match to the observed tectonic plate motions and to the global free-air gravity anomalies. Two distinct end-member models are considered in these inversions: a model that yields a whole-mantle style of flow and a strictly layered-flow model that includes an explicit mechanical barrier to vertical flow at 670 km depth. We find, after considering the uncertainties in the seismic tomographic model, that the convection-related surface observables predicted on the basis of the layered and whole-mantle flow models are indistinguishable. We consider here the implications of layered convection for the flow-induced deformation at the bottom of the upper mantle. We compare this deformation field with that predicted by a model which yields a whole-mantle style of flow. Significant differences are found in the predicted directions of maximum extension rate which may be related to seismic inferences of azimuthal anisotropy at the bottom of the upper mantle. We propose that a systematic study of deep-mantle anisotropy, particularly in the mantle transition zone, may provide the clearest constraints on the degree of vertical layering in the mantle convective flow." @default.
