1 Definition

1.1 Definition

Claystone is a fine-grained, dark gray to pink sedimentary rock which mainly consists of compacted and hardened clay

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

1.2 History

1.3 Etymology

From English clay and stone as the rock contains more amount of clay

From Latin Argilla (clay) and -ite in English which became agrilla+ -ite = Argillite

5.1 Formation

Claystone is generally quite soft, but can be hard and brittle. It forms due to weathering of mudstone.

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.

Claystone vs Argillite Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Claystone and Argillite Reserves. Claystone is a fine-grained, dark gray to pink sedimentary rock which mainly consists of compacted and hardened clay. 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. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Claystone vs Argillite information and Claystone vs Argillite characteristics in the upcoming sections.

More about Claystone and Argillite

Here you can know more about Claystone and Argillite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Claystone and Argillite consists of mineral content and compound content. The mineral content of Claystone includes Biotite, Chlorite, Feldspar, Micas, Muscovite or Illite, Plagioclase, Pyrite, Quartz and mineral content of Argillite includes Biotite, Chlorite, Feldspar, Micas, Muscovite or Illite, Plagioclase, Pyrite, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Claystone vs Argillite, the texture, color and appearance plays an important role in determining the type of rock. Claystone is available in black, blue, brown, green, grey, orange, red, white, yellow colors whereas, Argillite is available in dark grey to black, pink, red, white colors. Appearance of Claystone is Rough and Dull and that of Argillite is Rough and Dull. Properties of rock is another aspect for Claystone vs Argillite. The hardness of Claystone is 3.5-4 and that of Argillite is 2-3. The types of Claystone are Not Available whereas types of Argillite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Claystone is white while that of Argillite is white to grey. The specific heat capacity of Claystone is 0.92 kJ/Kg K and that of Argillite is 0.87 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Claystone is heat resistant, impact resistant whereas Argillite is heat resistant, impact resistant.
