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.

Basanite is a black basaltic rock which mainly contains plagioclase, augite, olivine and nepheline and is formerly used as a touchstone
From Latin basanites + -ite
Fine Grained Rock, Opaque Rock
Black, Brown, Green, Grey, Red, White
Decorative Aggregates, Homes
As Building Stone, Garden Decoration, Office Buildings
Arrowheads, Construction Aggregate, Cutting Tool, Spear Points
As a touchstone, Creating Artwork, Gemstone, In fire-starting tools, Manufacture of tools, Metallurgical Flux, Jewelry, To ignite fire, Used in flintlock firearms
Nepheline-Basanite, Analcite-Basanite and Leucite-Basanite
Clasts are smooth to touch, Easily splits into thin plates, Has High structural resistance against erosion and climate, Used as a touchstone
Basanite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.
