Definition
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
Marble is a non-foliated metamorphic rock which is composed of recrystallized carbonate which is formed when limestone is exposed to high temperatures and pressures over a long time

Formation
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.
Marble is a metamorphic rock produced from limestone in the earth crust. It is formed by the metamorphism of limestone.

All about Argillite and Marble Properties
Know all about Argillite and Marble properties here. All properties of rocks are important as they define the type of rock and its application. Argillite belongs to Sedimentary Rocks while Marble belongs to Metamorphic Rocks.Texture of Argillite is Clastic, Polished whereas that of Marble is Granular. Argillite appears Rough and Dull and Marble appears Veined and Shiny. The luster of Argillite is waxy and dull while that of Marble is dull to pearly to subvitreous. Argillite is available in dark grey to black, pink, red, white colors whereas Marble is available in black, blue, brown, grey, pink, white colors. The commercial uses of Argillite are fire resistant, used to manufracture paperweights and bookends and that of Marble are cemetery markers, commemorative tablets, creating artwork, curling, laboratory bench tops, paper industry, tombstones, used in aquariums, whiting material in toothpaste, paint and paper.
