A subduction zone is created where two plates converge, with one sinking into the mantle. Dynamics along the plate interface create earthquakes, magma generated above the sinking slab leads to ...

But how do they form and why are they concentrated there? (A) Diagram of a subduction zone illustrating the transfer of gold and sulfur from the subducting slab through the mantle to the upper crust ...

Slab pull occurs where older, denser tectonic plates sink into the mantle at subduction zones. As these older sections of plates sink, newer and less dense sections of plate are pulled along behind.
