WorldAtlas,Jul 28, 2017· Granite also occurs in lacoliths, dikes and sills. Other rock variations, similar in composition to granite, are alpites and pegmatites. Alpites with finer grain size than granite, occur at the margins of granitic intrusions. Pegmatites with coarser grains than granite often share locations with granite deposits.

Magma is found between the mantle and the crust of the earth, and often flows towards the surface of the earth. As the magma rises to the surface though it starts to cool down, and unless it finds an escape route, could solidify as an intrusive rock formation.
