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 Tuff and Lignite Reserves. Tuff is a type of rock made of volcanic ash ejected from a vent during a volcanic eruption. Lignite is a soft brownish coal which shows traces of plants and is intermediate between bituminous coal and peat. 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 Tuff vs Lignite information and Tuff vs Lignite characteristics in the upcoming sections.
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. Tuff vs Lignite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Tuff and Properties of Lignite. Learn more about Tuff vs Lignite in the next section. The interior uses of Tuff include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration whereas the interior uses of Lignite include Not yet used. Due to some exceptional properties of Tuff and Lignite, they have various applications in construction industry. The uses of Tuff in construction industry include Building houses or walls, Construction aggregate and that of Lignite include For road aggregate, Steel production.
Here you can know more about Tuff and Lignite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Tuff and Lignite consists of mineral content and compound content. The mineral content of Tuff includes Calcite, Chlorite and mineral content of Lignite is not available. You can also check out the list of all Igneous Rocks. When we have to compare Tuff vs Lignite, the texture, color and appearance plays an important role in determining the type of rock. Tuff is available in brown, grey, yellow colors whereas, Lignite is available in black, brown, dark brown, grey, light to dark grey colors. Appearance of Tuff is Dull, Vesicular and Foilated and that of Lignite is Veined or Pebbled. Properties of rock is another aspect for Tuff vs Lignite. The hardness of Tuff is 4-6 and that of Lignite is 1. The types of Tuff are Welded tuff, Rhyolitic tuff, Basaltic tuff, Trachyte tuff, Andesitic tuff and Ignimbrite. 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 Tuff is white while that of Lignite is black. The specific heat capacity of Tuff is 0.20 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.Tuff is heat resistant, impact resistant, pressure resistant, wear resistant whereas Lignite is heat resistant.
