Feldspars (KAlSi3O8 – NaAlSi3O8 – CaAl2Si2O8) are a group of rock-forming tectosilicate minerals that make up about 40% of the Earth's continental crust. Feldspars crystallize from magma as veins in both intrusive and extrusive igneous rocks and are also present in many types of metamorphic rock.

Feldspar is one of the most abundant minerals in the earth's crust. The feldspars include a range of compositions with a general chemical formula of xAl(Al,Si)3O8 where x can be sodium (Na) and/or calcium (Ca) and/or potassium (K).

Feldspar is the name given to a group of minerals distinguished by the presence of alumina and silica (SiO2) in their chemistry. This group includes aluminum silicates of soda, potassium, or lime. It is the single most abundant mineral group on Earth.

Feldspar consists essentially of aluminum silicates combined with varying percentages of potassium, sodium, and calcium, and it is the most abundant mineral of the igneous rocks. The two types of feldspar are. soda feldspar (7 percent or higher Na O) and potash feldspar (8 percent or higher K O).
