How is granite formed?

January 14, 2020

Granite is formed by a solidification of magma under the earth’s surface. As magma is forced between rocks, it starts to cool slowly to form large crystals. The crystals that make up granite are feldspar, mica, quartz, and other minerals that together create unique patterns and colors. This natural process takes millions of years to form, giving granite its strength with unique markings that make it special.

Here is a diagram of how granite is formed:

  1. A magma chamber forms.
  2. It slowly cools.
  3. Continued uplifting from tectonic action forms mountains.
  4. Erosion and continental glaciers scour the earth exposing the granite dome at the surface.
