Shale vs Lignite 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. Shale vs Lignite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Shale and Properties of Lignite. Learn more about Shale vs Lignite in the next section. The interior uses of Shale include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Lignite include Not yet used. Due to some exceptional properties of Shale and Lignite, they have various applications in construction industry. The uses of Shale in construction industry include Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for the manufacture of mortar and that of Lignite include For road aggregate, Steel production.
More about Shale and Lignite
Here you can know more about Shale and Lignite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Shale and Lignite consists of mineral content and compound content. The mineral content of Shale includes Albite, Biotite, Calcite, Chert, Chlorite, Dolomite, Hematite, Micas, Muscovite or Illite, Pyrite, Quartz, Silica, Sulfides and mineral content of Lignite is not available. You can also check out the list of all Sedimentary Rocks. When we have to compare Shale vs Lignite, the texture, color and appearance plays an important role in determining the type of rock. Shale is available in black, brown, buff, green, grey, red, yellow colors whereas, Lignite is available in black, brown, dark brown, grey, light to dark grey colors. Appearance of Shale is Muddy and that of Lignite is Veined or Pebbled. Properties of rock is another aspect for Shale vs Lignite. The hardness of Shale is 3 and that of Lignite is 1. The types of Shale are Red Shale, Black Shale, Green Shale, Grey Shale and Yellow Shale whereas types of Lignite are Xyloid Lignite or Fossil Wood and Compact Lignite or Perfect Lignite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Shale is white while that of Lignite is black. The specific heat capacity of Shale is 0.39 kJ/Kg K and that of Lignite is 1.26 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Shale is heat resistant, impact resistant whereas Lignite is heat resistant.
