Granite, Basalt, Obsidian, Pumice and many others . Igneous Rocks are records of the thermal history of Earth. Most common of all rocks is Granite: . Granite . is a light-colored . igneous rock.  with grains large enough to be visible with the unaided eye.  It forms from the slow crystallization of magma below Earth’s surface.  Granite is composed mainly of quartz and  feldspar with minor amounts of mica, amphiboles and other minerals.   This mineral composition usually gives granite a red, pink, gray or white color with dark mineral grains visible throughout the rock.
