The thermal history of a granite—how fast it cooled and how long it spent at different temperatures—dictates the size of the mineral grains, and thus the rock texture. A prime example is the Cathedral Peak Granodiorite, which has unusually large (up to 3 inches long) crystals of potassium feldspar that are thought to have formed through episodic heating and cooling of the magma. This type of rock dominates the landscape in the Yosemite high country near Tuolumne Meadows.

In these zones, the input of water-rich oceanic crust causes partial melting at the base of the crust about 25 to 30 miles below the earth’s surface. The resulting magma is less dense than material typically found at that depth, so it rises like oil in salad dressing. This is the silica-rich magma that is often violently expelled from the large volcanos, like Mt. Saint Helens and Mt. Rainier, which sit above subduction zones today.
