Seismic waves that travel along the surface of subducted slabs provide a means to infer petrology to considerable depth. At high frequencies (0.5-10 Hz) they are particularly sensitive to the presence and state of subducted ...

We present a melt percolation model incorporating finite solid diffusion to provide a quantitative constraint on how melt migrates through the oceanic lower crust at fast-spreading ridge axes. The lower crustal, layered ...

Experiments in the basalt-H2O system at 600–950°C and 0.8–3.0 GPa, demonstrate that breakdown of amphibole represents the final dehydration of subducting oceanic tholeiite at T≥650°C; the dehydration H2O occurs as a free ...

The most common model used for representing the evolution with age of the oceanic lithosphere is the 'plate model' where the temperature is set at a fixed depth, called the base of the plate. This 'base of the plate' has ...
