Some of the effects of the stresses associated with these regions can be seen in inclined planes known as Wadati-Benioff zones.
Some of the effects of the stresses associated with these regions can be seen in inclined planes known as Wadati-Benioff zones. Tomographic imaging indicates that the motions associated with these regions can extend through the 670 km discontinuity, occasionally reaching the Gutenberg discontinuity. Surface features associated with these regions include volcanic and island arcs formed from andesitic magma derived from mantle material and sediments melted off of the affected slab, which must consist of oceanic plate material. FTP, name this type of convergent plate boundary in which one plate descends under another plate into the mantle.
