Alkali feldspar granite

The abundance of K-spar gives the rock a predominant pink to reddish hue; peppered with minor amounts of black minerals.

[4] Other incorporated silicate minerals may include, very minor amounts of plagioclase feldspar, mica in the form of muscovite and/or biotite, and amphibole (often hornblende).

They are found in a wide range of tectonic settings and their origins remain uncertain.

[5] Granitic rocks in general are of interest to geologists, geochemists, etc., because they provide 'crystallized' telltale clues of their environment of formation.

[6] Alkali feldspar granite is used as construction material in the form of dimension stones, and polished slabs or tiles for building facades, pavements, and kitchen countertops.
