Limestone vs Argillite

Limestone 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 Limestone and Argillite Reserves. Limestone is a sedimentary rock composed mostly of calcite and aragonite, which are different crystal forms of calcium carbonate. 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 Limestone vs Argillite information and Limestone vs Argillite characteristics in the upcoming sections.

Limestone 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. Limestone vs Argillite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Limestone and Properties of Argillite. Learn more about Limestone vs Argillite in the next section. The interior uses of Limestone include Decorative aggregates and Interior decoration whereas the interior uses of Argillite include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Limestone and Argillite, they have various applications in construction industry. The uses of Limestone in construction industry include Cement manufacture, Cobblestones, For road aggregate, Production of glass and ceramics, Raw material for the manufacture of mortar, Roadstone, Source of calcium and that of Argillite include Used for flooring, stair treads, borders and window sills..

More about Limestone and Argillite

Here you can know more about Limestone and Argillite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Limestone and Argillite consists of mineral content and compound content. The mineral content of Limestone includes Calcite, Chert, Clay, Dolomite, Quartz, Sand, Silt 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 Limestone vs Argillite, the texture, color and appearance plays an important role in determining the type of rock. Limestone is available in beige, black, blue, brown, cream, gold, green, grey, light green, light grey, linen, pink, red, rust, silver, white, yellow colors whereas, Argillite is available in dark grey to black, pink, red, white colors. Appearance of Limestone is Rough and Banded and that of Argillite is Rough and Dull. Properties of rock is another aspect for Limestone vs Argillite. The hardness of Limestone is 3-4 and that of Argillite is 2-3. The types of Limestone are Chalk, Coquina, Fossiliferous Limestone, Lithographic Limestone, Oolitic Limestone, Travertine, Tufa 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 Limestone is white while that of Argillite is white to grey. The specific heat capacity of Limestone is 0.91 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.Limestone is pressure resistant whereas Argillite is heat resistant, impact resistant.
