Argillite vs Lignite

Argillite vs Lignite 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 Argillite and Lignite Reserves. Argillites are highly compact sedimentary or slightly metamorphosed rocks that consist largely or wholly of particles of clay or silt but lack the fissility of shale or the cleavage characteristic of slate. 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 Argillite vs Lignite information and Argillite vs Lignite characteristics in the upcoming sections.

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

You can also check out the list of all Sedimentary Rocks. When we have to compare Argillite vs Lignite, the texture, color and appearance plays an important role in determining the type of rock. Argillite is available in dark grey to black, pink, red, white colors whereas, Lignite is available in black, brown, dark brown, grey, light to dark grey colors. Appearance of Argillite is Rough and Dull and that of Lignite is Veined or Pebbled. Properties of rock is another aspect for Argillite vs Lignite. The hardness of Argillite is 2-3 and that of Lignite is 1. The types of Argillite are Not Available 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 Argillite is white to grey while that of Lignite is black. The specific heat capacity of Argillite is 0.87 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.Argillite is heat resistant, impact resistant whereas Lignite is heat resistant.
