Partial melting of the thin, hot lithosphere inherited from the opening of the Mascarene backarc basin would have been promoted by upwelling and decompressional melting of the asthenospheric mantle following slab-break-off.
Petrological and geochemical data is consistent with the basaltic, doleritic and gabbroic intrusions comprising alkalic series signatures, characteristic of heterogeneous asthenospheric melting associated with ocean island basalt (OIB) magmatism.
The results of deep geophysical detection can provide substantial evidence for asthenospheric material flow within the lower crust.
Kadioglu & Dilek (2010) suggested that the HP shows chemical characteristics of high-Al adakitic compositions, which could have formed by the partial melting of the hydrated lithospheric mantle and the amphibolitic mafic lower crust that was triggered by delamination-induced asthenospheric upwelling.
3]), the change from positive to negative values in the magnitude of the stress anomalies, indicates the level at which the negative normal stress anomalies from the crustal material reach an equilibrium with the higher stress created by the asthenospheric material.
This mass excess is yielded by the replacement beneath the southwestern end of the model of a relatively low-density asthenospheric mantle with a high-density lithospheric mantle.
103) This implies that the asthenospheric electrical anisotropy, if any observation suggests, should be ascribed to other mechanism such as macroscopic heterogeneity.
2010) attributed these morphologic elevations to pre-eruptive tectonic uplift of the basement, corroborating the model of solid-state penetration of asthenospheric hot-mantle along the old abyssal fracture zone from the west to the east.
We have imposed a narrow 'low viscosity conduit' of asthenospheric material connecting the lower crust with the asthenosphere adjacent to the orogenic root.
Robertson discusses the roles of asthenospheric shear, inherited lithospheric weaknesses, and slab pull from a neighbouring subduction zone as causative agents for Tethyan rift sequences now exposed in Oman.
For the numerical simulations we use the so-called isostatic model, based on the concept that the elevation of earth's surface seeks a balance between the weight of lithospheric rocks and the buoyancy of asthenospheric "fluid" (nearly-molten rock).
