Feldspar is the name of a group of rock-forming minerals which make up as much as 60% of the Earth''s crust.. Feldspars crystallize from magma in both intrusive and extrusive rocks, and they can also occur as compact minerals, as veins, and are also present in many types of metamorphic rock. Rock formed entirely of plagioclase feldspar (see below) is known as anorthosite.

This makes it an ideal projection for mafic rocks; however, it is less suitable for granitic rocks because K-feldspar and albite plot at the same point. This means that the diagram cannot be used to distinguish between rocks with variable K/Na ratios and that most granitic rocks plot in a small area of the diagram ( Bachelor & Bowden, 1985 ).
