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.
Asthenospheric upwelling initiated crustal thinning, reactivated structures, and provided a heat source to circulate fluids on a regional scale.
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.
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.
