Formation

Coal formation takes place due to accumulation of plant debris in a swamp environment. The Coal formation process continues, as peat turns into lignite brown or black coal at increasing heat and pressure.

Wackestone is a type of sedimentary rock formed when a river carries or transports pieces of broken rock as it flows. These particles settle down and are then compacted due to high temperature and pressure hence forming Wackestone.

More about Lignite and Wackestone

Here you can know more about Lignite and Wackestone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Lignite and Wackestone consists of mineral content and compound content. The mineral content of Lignite includes and mineral content of Wackestone includes Biotite, Chlorite, Feldspar, Micas, Muscovite or Illite, Plagioclase, Pyrite, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Lignite vs Wackestone, the texture, color and appearance plays an important role in determining the type of rock. Lignite is available in black, brown, dark brown, grey, light to dark grey colors whereas, Wackestone is available in black, blue, brown, green, grey, orange, red, white, yellow colors. Appearance of Lignite is Veined or Pebbled and that of Wackestone is Rough and Dull. Properties of rock is another aspect for Lignite vs Wackestone. The hardness of Lignite is 1 and that of Wackestone is 2-3. The types of Lignite are Xyloid Lignite or Fossil Wood and Compact Lignite or Perfect Lignite whereas types of Wackestone are Marl, Shale and Argillite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Lignite is black while that of Wackestone is white. The specific heat capacity of Lignite is 1.26 kJ/Kg K and that of Wackestone is 0.39 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Lignite is heat resistant whereas Wackestone is heat resistant, impact resistant.
