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 …

Mining crushed stone is more involved because the deposits are consolidated, meaning solid rock formations. The most common types of crushed stone come from deposits of limestone, dolomite and granite. To produce crushed stone, the massive formation first is drilled with a pattern of holes loaded with explosives by a licensed blaster.
