Hauki quartzite (Swedish: Haukikvartsiten) is a rock unit of quartz arenite found in northernmost Sweden.
[1] More arkosic parts are of reddish colour but otherwise made of light grey rocks.
[1][2] Apart from quart arenite the unit hosts some conglomerates with clasts of phyllite and quartz porphyry.
[2] The clasts are derived from the nearby units of Hopukka Formation, Loussavaara Formation and Matojärvi Formation.
