Feldspar forms in a variety of geological settings, from deep within the Earth's crust to the cooling lava of a volcano. This diversity in formation environments is a big reason why there are so many different types of feldspar. The range of colors seen in feldspar is due to trace elements and impurities that get mixed in during its formation.
