What type of plate boundary leads to subduction? Convergent plate boundaries lead to subduction. Subduction occurs  when one tectonic plate rides over the edge of another tectonic  plate which sinks into the mantle as theyâ¦ converge.
Three types of convergent boundaries are recognized: continentâcontinent, oceanâcontinent, and oceanâocean. Continentâcontinent convergence results when two continents collide. The continents were separated at one time by oceanic crust that was progressively subducted under one of the continents.
