Definition
Alkali feldspar granite, also known as red granite, is a felsic igneous rock and a type of granite rich in the mineral potassium feldspar
Argillites are highly compact sedimentary or slightly metamorphosed rocks that consist largely or wholly of particles of clay or silt but lack the fissility of shale or the cleavage characteristic of slate

Etymology
From mineral fledspar which is present in large quantities in this rock
From Latin Argilla (clay) and -ite in English which became agrilla+ -ite = Argillite

Formation
Alkali fledspar granite is an intrusive igneous rock which is very hard, crystalline and is visibly homogeneous in texture and forms by melting of continental rocks.
An argillite is a fine-grained sedimentary rock mainly composed of clay particles which forms from lithified muds which contain variable amounts of silt-sized particles.
