Subduction zones are where sediments, oceanic crust, and mantle lithosphere return to and
reequilibrate with Earth's mantle. Subduction zones are interior expressions of Earth's …

Seismic anisotropy is caused mainly by the lattice-preferred orientation of anisotropic
minerals. Major breakthroughs have occurred in the study of lattice-preferred orientation in …

55 4.4 Experimental techniques 57 4.5 Some general trends in elasticity: Birch's law 59 4.6 …

The compositions of back-arc basin basalts (BABB) can usefully be viewed as products of
four factors:(1) the composition of inflowing mantle and its preconditioning during flow to the …

The interpretation of seismic anisotropy in Earth's upper mantle has traditionally been based
on the fabrics (lattice-preferred orientation) of relatively water-poor olivine. Here we show …

Observations of seismic anisotropy yield some of the most direct constraints available on
both past and present-day deformation in the Earth's mantle. Insight into the character of …

Slab edges are a relatively common feature in plate tectonics. Two prominent examples are
the northern end of the Tonga subduction zone and the southern end of the New Hebrides …

Statistical analysis of modern oceanic subduction zone parameters, such as the age of a
downgoing plate or the absolute plate motions, is performed in order to investigate which …

A Cenozoic tectonic reconstruction is presented for the Southwest Pacific region located
east of Australia. The reconstruction is constrained by large geological and geophysical …

Back-arc extension or compression is often related to a particular behavior of the slab (dip
change and/or forward/backward migration) with respect to the upper plate. Slabs act, either …
