Coal vs Chert

Coal vs Chert 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 Chert Reserves. Coal is a combustible black or brownish-black sedimentary rock usually occurring in rock strata in layers called coal beds. Chert is a hard, dark, opaque sedimentary rock which is composed of silica with an amorphous fine-grained texture. 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 Chert information and Coal vs Chert characteristics in the upcoming sections.

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

Coal is available in black, brown, dark brown, grey, light to dark grey colors whereas, Chert is available in black, brown, green, grey, red, white colors. Appearance of Coal is Veined or Pebbled and that of Chert is Glassy or Pearly. Properties of rock is another aspect for Coal vs Chert. The hardness of Coal is 1-1.5 and that of Chert is 6.5-7. The types of Coal are Peat, Lignite, Sub-Bituminous Coal, Bituminous Coal, Anthracite, Graphite whereas types of Chert are Flint, Jasper, Radiolarite, Common Chert, Chalcedony, Agate, Onyx, Opal, Magadi-type Chert, Porcelanite, Siliceous Sinter. 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 Chert is white. The specific heat capacity of Coal is 1.32 kJ/Kg K and that of Chert is 0.74 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 Chert is heat resistant, impact resistant, pressure resistant, wear resistant.
