Hornblendite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

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.

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.
