Subduction zones are characterized by active volcanism due to the melting of the subducted oceanic plate beneath the overriding plate, which is not a feature of collisional mountain chains. Collisional mountain chains form when two continental plates collide, and neither plate is forced under the other, so there's no subduction and thus no related volcanism.
