Geophysical evidence for lithospheric delamination beneath the Alboran Sea and Rif-Betic mountains
Article Abstract:
Geophysical evidence has been obtained on the occurrence of lithospheric delamination beneath the Alboran Sea and the surrounding Rif and Betic mountain belts of the western Mediterranean. The most significant proof of active delamination in the sites is the occurrence of intermediate-depth tremors and their spatial distributions. A tectonic event which occurred in the early Miocene is believed to have caused instability within the lithosphere which has possibly become the driving mechanism for active delamination.

Discrete alternating hotspot islands formed by interaction of magma transport and lithospheric flexure
Article Abstract:
There have been various models to explain the formation of discrete islands within hotspot tracks. The hypothesis that island spacing is regulated by lithospheric flexure has been used to develop a nonlinear model coupling magma flow, feeding volcanic growth to the flexure due to volcanic loads. The current Kea and Loa trends of the Hawaiian islands are predicted by the model to be due to an off-axis asymmetry caused by a changes in direction of plate motion.

From mountains to basin
Article Abstract:
Geophysical evidence has been presented on the process of lithospheric delamination occurring beneath the western Mediterranean. Observations of the Alboran Sea have shown the consequences of lithospheric delamination. However, since only the consequences are observed, then it is difficult to determine whether lithospheric thinning is more like delamination or more like convective thinning.
