In Geology. A convergent boundary with no subduction is a continental-continental boundary. Because oceanic crust is denser than continental crust, it is always the subducting plate in a â¦ oceanic-continental boundary.In an oceanic-oceanic boundary, one of the plates will subduct, depending on several factors.ecause oceanic crust is denser than continental crust, it is always the subducting plate in a â¦ oceanic-continental boundary. In an oceanic-oceanic boundary, one of the plates will subduct, depending on several factors.
Subduction zones are convergent boundaries where at least one of the tectonic plates is an oceanic crust. The new oceanic crust that forms in spreading centers is recycled in these zones.Subducting oceanic plate. The oceanic crust melts as it descends into the lithosphere and upper mantle.ubduction zones are convergent boundaries where at least one of the tectonic plates is an oceanic crust. The new oceanic crust that forms in spreading centers is recycled in these zones. Subducting oceanic plate.
