Coal vs Nephelinite

Coal vs Nephelinite 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 Coal and Nephelinite Reserves. Coal is a combustible black or brownish-black sedimentary rock usually occurring in rock strata in layers called coal beds. Nephelinite is a fine-grained or aphanitic igneous rock made up almost entirely of nepheline and clinopyroxene (variety augite).. 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 Coal vs Nephelinite information and Coal vs Nephelinite characteristics in the upcoming sections.

Coal vs Nephelinite 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 Nephelinite characteristics assist us to distinguish and recognize rocks.

Coal is available in black, brown, dark brown, grey, light to dark grey colors whereas, Nephelinite is available in black, brown, colourless, green, grey, white colors. Appearance of Coal is Veined or Pebbled and that of Nephelinite is Skeletal. Properties of rock is another aspect for Coal vs Nephelinite. The hardness of Coal is 1-1.5 and that of Nephelinite is 6.5. The types of Coal are Peat, Lignite, Sub-Bituminous Coal, Bituminous Coal, Anthracite, Graphite whereas types of Nephelinite are Peralkaline Nephelinite. 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 Nephelinite is white. The specific heat capacity of Coal is 1.32 kJ/Kg K and that of Nephelinite is 0.88 kJ/Kg K. 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 Nephelinite is heat resistant.
