Coal vs Phonolite 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. Coal vs Phonolite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Coal and Properties of Phonolite. Learn more about Coal vs Phonolite in the next section.

Due to some exceptional properties of Coal and Phonolite, they have various applications in construction industry. The uses of Coal in construction industry include Cement manufacture, For road aggregate, Making natural cement, Steel production and that of Phonolite 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.
More about Coal and Phonolite
Here you can know more about Coal and Phonolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Coal and Phonolite consists of mineral content and compound content. The mineral content of Coal includes Analcime, Apatite, Barite, Calcite, Chalcopyrite, Chlorite, Chromite, Clausthalite, Clay Minerals, Crandallite Group, Dolomite, Feldspar, Galena, Gypsum, Marcasite, Muscovite or Illite, Pyrite, Quartz, Siderite, Sphalerite, Zircon and mineral content of Phonolite includes Albite, Amphibole, Biotite, Cancrinite, Feldspar, Hornblende, Plagioclase, Pyroxene, Sodalite.

Coal is available in black, brown, dark brown, grey, light to dark grey colors whereas, Phonolite is available in brown, buff, cream, green, grey, pink, white colors. Appearance of Coal is Veined or Pebbled and that of Phonolite is Banded and Foilated. Properties of rock is another aspect for Coal vs Phonolite. The hardness of Coal is 1-1.5 and that of Phonolite is 5.5-6. The types of Coal are Peat, Lignite, Sub-Bituminous Coal, Bituminous Coal, Anthracite, Graphite whereas types of Phonolite are Kenyte. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Coal is black while that of Phonolite is white. The specific heat capacity of Coal is 1.32 kJ/Kg K and that of Phonolite is Not Available. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Coal is heat resistant whereas Phonolite is heat resistant, impact resistant, wear resistant.
