Addendum: Differentiation of magma (fractional crystallization) also plays a big role in creating felsic magmas from mafic magmas. Also, granite can form at convergent boundaries that involve continental crust only (e.g., Indian and Asian plates).
Convergent Plate Boundaries. Convergent boundaries form where two plates collide. These boundaries often form major mountain chains. These boundaries are identified by their high mountains, volcanic island arc chains, and deep earthquakes.An ocean plate converges with a continental plate.ivergent Plate Boundaries. Divergent boundaries can be mid-ocean ridges or continental rift valleys. At these boundaries, two neighboring plates move away from each other. Continental rift valleys are characterized by normal faulting and basalt-rich volcanoes.
