Granulite vs Argillite

Definition

Definition

Granulite is fine to medium grained metamorphic rock with a granular of polygonal crystals.
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

Formation

Formation

Granulite is a fine-grained granular metamorphic rock in which the main component minerals are feldspars and quartz and forms at high temperature and pressure conditions.
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.

Granulite 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 Granulite and Argillite Reserves. Granulite is fine to medium grained metamorphic rock with a granular of polygonal crystals.. 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 Granulite vs Argillite information and Granulite vs Argillite characteristics in the upcoming sections.

Granulite 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. Granulite vs Argillite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Granulite and Properties of Argillite. Learn more about Granulite vs Argillite in the next section. The interior uses of Granulite include Bathrooms, Countertops, Decorative aggregates, Entryways, Flooring, Homes, Hotels, Interior decoration, Kitchens and Stair treads whereas the interior uses of Argillite include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Granulite and Argillite, they have various applications in construction industry. The uses of Granulite in construction industry include As dimension stone, Building houses or walls and that of Argillite include Used for flooring, stair treads, borders and window sills..

More about Granulite and Argillite

Here you can know more about Granulite and Argillite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Granulite and Argillite consists of mineral content and compound content. The mineral content of Granulite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, 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 Metamorphic Rocks. When we have to compare Granulite vs Argillite, the texture, color and appearance plays an important role in determining the type of rock. Granulite is available in black, brown colors whereas, Argillite is available in dark grey to black, pink, red, white colors. Appearance of Granulite is Veined or Pebbled and that of Argillite is Rough and Dull. Properties of rock is another aspect for Granulite vs Argillite. The hardness of Granulite is 6-7 and that of Argillite is 2-3. The types of Granulite are Metamorphic rock 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 Granulite is white while that of Argillite is white to grey. The specific heat capacity of Granulite is 0.14 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.Granulite is heat resistant, wear resistant whereas Argillite is heat resistant, impact resistant.
