1 Definition

1.1 Definition

Phonolite is an uncommon extrusive igneous rock volcanic rock of intermediate chemical composition between felsic and mafic

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

Unknown

1.2.2 Discoverer

Unknown

1.3 Etymology

From the Greek meaning sounding stone because of the metallic sound it produces if an unfractured plate is hit

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

5.1 Formation

Phonolite are formed due to alkaline igneous activities and are generally formed in thick continental crustal areas or in Cordilleran subduction zones.

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.

Phonolite 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 Phonolite and Argillite Reserves. Phonolite is an uncommon extrusive igneous rock volcanic rock of intermediate chemical composition between felsic and mafic. 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 Phonolite vs Argillite information and Phonolite vs Argillite characteristics in the upcoming sections.

Phonolite 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. Phonolite vs Argillite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Phonolite and Properties of Argillite. Learn more about Phonolite vs Argillite in the next section. The interior uses of Phonolite include Countertops, Decorative aggregates, Flooring and Homes whereas the interior uses of Argillite include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Phonolite and Argillite, they have various applications in construction industry. The uses of Phonolite in construction industry include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Landscaping, Making natural cement, Manufacture of magnesium and dolomite refractories, Production of glass and ceramics and that of Argillite include Used for flooring, stair treads, borders and window sills..

More about Phonolite and Argillite

Here you can know more about Phonolite and Argillite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Phonolite and Argillite consists of mineral content and compound content. The mineral content of Phonolite includes Albite, Amphibole, Biotite, Cancrinite, Feldspar, Hornblende, Plagioclase, Pyroxene, Sodalite 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 Igneous Rocks. When we have to compare Phonolite vs Argillite, the texture, color and appearance plays an important role in determining the type of rock. Phonolite is available in brown, buff, cream, green, grey, pink, white colors whereas, Argillite is available in dark grey to black, pink, red, white colors. Appearance of Phonolite is Banded and Foilated and that of Argillite is Rough and Dull. Properties of rock is another aspect for Phonolite vs Argillite. The hardness of Phonolite is 5.5-6 and that of Argillite is 2-3. The types of Phonolite are Kenyte 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 Phonolite is white while that of Argillite is white to grey. The specific heat capacity of Phonolite is Not Available 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.Phonolite is heat resistant, impact resistant, wear resistant whereas Argillite is heat resistant, impact resistant.
