Final answer:
At a convergent margin, rocks such as igneous rocks, high-grade metamorphic rocks, and ophiolites can occur.
Step-by-step explanation:
At a convergent margin, where two tectonic plates collide, several types of rocks can occur. In the Central Andes Mountains, which is an example of an active convergent margin, both intrusive and extrusive igneous rocks formed during the Neogene period. These volcanic rocks are overlain by more recent volcanoes. Near the center of a continental collision, high-grade metamorphic rocks can be found. These rocks are formed by the intense heat and pressure created during the collision. In addition, ophiolites, which are sequences of igneous rocks derived from the decompression melting of Earth's mantle, can be exposed during the final stages of subduction in convergent margins.
