Quizplus · Accepted Answer

Subduction-related magmatism occurs when one tectonic plate subducts beneath another plate. In a continental collision, both continents are too buoyant to subduct, so subduction-related magmatism would not occur on either continent. However, the collision can cause melting of the crust and mantle, leading to magmatism on the edges of the continents where the collision is occurring. In this figure, the continent on the right (with the arrow pointing towards it) is experiencing more deformation and compression, indicating that the collision is occurring on that side. Therefore, this continent is more likely to have subduction-related magmatism.
