Stonehenge in English county of Wiltshire
Diabase forms when molten igneous rock is squeezed up into a vertical crack in other rocks, the crack is usually forced apart and the molten rock cools in the space to form a tabular igneous intrusion cutting across the surrounding rocks and is known as a dike.

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

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.
