Alkali feldspar granite Alkali feldspar granite Alkali feldspar granite, some varieties of which are called 'red granite', is a felsic igneous rock and a type of granite rich in the mineral potassium feldspar (K-spar). It is a dense rock with a phaneritic texture. The abundance of K-spar gives the rock a predominant pink to reddish hue; peppered with minor amounts of black minerals.

More than 90% of the total feldspar content is in the form of alkali feldspar.

Granite Rock Co., 480 U.S. 572 (1987), is a United States Supreme Court case addressing the question of whether United States Forest Service regulations, federal land use statutes and regulations, or the Coastal Zone Management Act of 1972, preempt the California Coastal Commission's imposition of a permit requirement on operation of an unpatented mining claim in a national forest.
