Variation in styles of rifting in the Gulf of California
Article Abstract:
The PESCADOR seismic experiment is conducted in the southern Gulf of California and the crustal-scale images across three rift segments are presented. The results have shown that mantle depletion, rather than low mantle temperature, has accounted for the wide, magma-poor margins, and that mantle fertility and sedimentary insulation, rather than high mantle temperature, has accounted for the robust rift and post-rift magmatism.

Magma-assisted rifting in Ethiopia
Article Abstract:
An evidence of seismic anisotropy in the upper mantle of the Northern Ethiopian Rift zone is presented using observations of shear-wave splitting. The observations indicate a strong component of melt-induced anisotropy with only minor crustal stretching, supporting the magma-assisted rifting model in this area of initially cold, thick continental lithosphere.

Spreading-rate dependence of melt extraction at mid-ocean ridges from mantle seismic refraction data
Article Abstract:
The study presents the results of a seismic refraction experiment designed to study mid-ocean ridge processes by imaging residual mantle structure. The results revealed an abrupt lateral change in bulk mantle seismic properties associated with a change from slow to ultraslow palaeo-spreading rate.
