Phyllite is a fine-grained metamorphic rock with a well-developed laminar structure, and is intermediate between slate and schist rocks
From Greek phullon leaf + -ite1

Easily splits into thin plates, Is one of the oldest rock, Surfaces are often shiny
Phyllite is a metamorphic rock which is formed by regional metamorphism of argillaceous sediments since their cleavage arose due to deviatoric stress.

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
From Latin Argilla (clay) and -ite in English which became agrilla+ -ite = Argillite
Fine Grained Rock, Opaque Rock
Dark Grey to Black, Pink, Red, White

Fire resistant, Used to manufracture paperweights and bookends
Is one of the oldest rock
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.
