Phonolite vs Coal

Phonolite vs Coal 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 Coal Reserves. Phonolite is an uncommon extrusive igneous rock volcanic rock of intermediate chemical composition between felsic and mafic. Coal is a combustible black or brownish-black sedimentary rock usually occurring in rock strata in layers called coal beds. 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 Coal information and Phonolite vs Coal characteristics in the upcoming sections.

Phonolite vs Coal 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 Coal characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Phonolite and Properties of Coal. Learn more about Phonolite vs Coal in the next section. The interior uses of Phonolite include Countertops, Decorative aggregates, Flooring and Homes whereas the interior uses of Coal include Not yet used. Due to some exceptional properties of Phonolite and Coal, 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 Coal include Cement manufacture, For road aggregate, Making natural cement, Steel production.

More about Phonolite and Coal

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

Phonolite is available in brown, buff, cream, green, grey, pink, white colors whereas, Coal is available in black, brown, dark brown, grey, light to dark grey colors. Appearance of Phonolite is Banded and Foilated and that of Coal is Veined or Pebbled. Properties of rock is another aspect for Phonolite vs Coal. The hardness of Phonolite is 5.5-6 and that of Coal is 1-1.5. The types of Phonolite are Kenyte whereas types of Coal are Peat, Lignite, Sub-Bituminous Coal, Bituminous Coal, Anthracite, Graphite. 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 Coal is black. The specific heat capacity of Phonolite is Not Available and that of Coal is 1.32 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 Coal is heat resistant.
