What is granite?
Granite is a felsic intrusive igneous rock consisting primarily of quartz, potassium feldspar (e.g., orthoclase or microcline) or plagioclase feldspar (albite, or labradorite), mica (e.g., muscovite or biotite), and amphiboles (e.g., hornblende). Granites make up much of the intrusive mass of continental crust forming huge plutons (e.g. batholiths or lacoliths) that may be over 100 […]
