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).
Examples of Convergent Boundaries. The west coast of South America is a convergent boundary between the Nazca plate and the South American plate. The collision of this oceanic and continental plate was how the Andes mountains were formed.Convergent boundaries can also form islands.The northern part of the Pacific Plate is subducting under the North American Plate, and the result is the formation of the Aleutian Islands.he collision of this oceanic and continental plate was how the Andes mountains were formed.
