  • Granite: Igneous Rock - Pictures, Definition & More

    What 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

  • How Are Granite Countertops Made? Hunker

    The manufacture of granite countertops begins with mining dimensional granite from quarries. Dimensional means that the rock is cut in whole pieces as opposed to quarried for crushed stone.
