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.
The subducting plate in a subduction zone is normally oceanic crust, and moves beneath the other plate, which can be made of either oceanic or continental crust. During collisions between two continental plates, large mountain ranges, such as the Himalayas are formed. In other regions, a divergent boundary or transform faults may be present.
