Definition
Enderbite rock is an igneous rock which belongs to the Charnockite rock series
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

Formation
Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing 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.
