Schist vs Argillite

Schist 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 Schist and Argillite Reserves. Schist is a medium grade metamorphic rock with medium to large, flat, sheet like grains in a preferred orientation. 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 Schist vs Argillite information and Schist vs Argillite characteristics in the upcoming sections.

Schist vs Argillite Characteristics

Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Schist vs Argillite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Schist and Properties of Argillite. Learn more about Schist vs Argillite in the next section. The interior uses of Schist include Decorative aggregates, Floor tiles and Interior decoration whereas the interior uses of Argillite include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Schist and Argillite, they have various applications in construction industry. The uses of Schist in construction industry include As dimension stone, Building houses or walls, Cement manufacture, For road aggregate, Roadstone and that of Argillite include Used for flooring, stair treads, borders and window sills..

More about Schist and Argillite

Here you can know more about Schist and Argillite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock.

You can also check out the list of all Metamorphic Rocks. When we have to compare Schist vs Argillite, the texture, color and appearance plays an important role in determining the type of rock. Schist is available in black, blue, brown, dark brown, green, grey, silver colors whereas, Argillite is available in dark grey to black, pink, red, white colors. Appearance of Schist is Layered and Shiny and that of Argillite is Rough and Dull. Properties of rock is another aspect for Schist vs Argillite. The hardness of Schist is 3.5-4 and that of Argillite is 2-3. The types of Schist are Mica Schists, Calc-Silicate Schists, Graphite Schists, Blueschists, Whiteschists, Greenschists, Hornblende Schist, Talc Schist, Chlorite Schist, Garnet Schist, Glaucophane schist. whereas types of Argillite are Metamorphic rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Schist is white while that of Argillite is white to grey. The specific heat capacity of Schist is 0.70 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.Schist is impact resistant, pressure resistant, water resistant whereas Argillite is heat resistant, impact resistant.
