1 Definition

1.1 Definition

Travertine is a mineral consisting of layered calcium carbonate formed by deposition from spring waters

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

5 Formation

5.1 Formation

Travertine is a type of sedimentary rock formed when a river carries or transports pieces of broken rock which then undergo sedimentation. They are then subjected to high temperature and pressure hence forming travertine 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.

Travertine 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 Travertine and Argillite Reserves. Travertine is a mineral consisting of layered calcium carbonate formed by deposition from spring waters. 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.

More about Travertine and Argillite

Here you can know more about Travertine and Argillite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Travertine and Argillite consists of mineral content and compound content. The mineral content of Travertine includes Calcite, Clay, Feldspar, Micas, 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 Travertine vs Argillite, the texture, color and appearance plays an important role in determining the type of rock. Travertine is available in beige, black, blue, brown, grey, red, white, yellow colors whereas, Argillite is available in dark grey to black, pink, red, white colors. Appearance of Travertine is Fibrous and that of Argillite is Rough and Dull. Properties of rock is another aspect for Travertine vs Argillite. The hardness of Travertine is 3-4 and that of Argillite is 2-3. The types of Travertine 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 Travertine is white while that of Argillite is white to grey. The specific heat capacity of Travertine is 1.09 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.Travertine is impact resistant, pressure resistant, wear resistant whereas Argillite is heat resistant, impact resistant.
