Feldspar Group
The feldspar group is one of the most common types of minerals in the earth's crust. Feldspar alteration (including the whole processes of feldspar dissolution, transfer of released solutes, and secondary mineral precipitation) is ubiquitous and important in fields including resources and environmental sciences.

The 12 Different Types Of Feldspar (With High-Quality Photos)
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.
