Feldspars (KAlSi₃O₈ - NaAlSi₃O₈ - CaAl₂Si₂O₈) are a group of rock-forming tectosilicate minerals which make up as much as 60% of the Earth‘s crust.^[1]

Feldspars crystallize from magma in both intrusive and extrusive igneous rocks, as veins, and are also present in many types of metamorphic rock.^[2] Rock formed almost entirely of calcic plagioclase feldspar (see below) is known as anorthosite.^[3] Feldspars are also found in many types of sedimentary rock.^[4]
