Hi I'm Jane Stammer from the Colorado School of Mines and I'm here to answer questions on how to identify granite. Granite is a type of igneous rock that is found all over the world and is a very abundant rock. The three main minerals in a granite are quartz, pladgoclez and potassium feldspar. Granites are usually light in color and have particularly medium to coarse green minerals in them.
