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
Decorative Aggregates, Homes, Interior Decoration
As Building Stone, Garden Decoration, Office Buildings
Used for flooring, stair treads, borders and window sills.
Artifacts, Monuments, Sculpture
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.

Anthracite is a type of sedimentary rock which is hard and is variety of coal that has high luster
From Greek anthrakites, from anthrax, anthrak meaning coal
Coarse Grained Rock, Fine Grained Rock, Medium Grained Rock, Opaque Rock

Semi-anthracite and Meta-anthracite
Helps in production of Heat and Electricity, Used as fossil fuel
Anthracite forms from the accumulation of plant debris in a swamp environment. When plant debris dies and falls into the swamp, the standing water of the swamp protects it from decay.
