Archaeological Significance
Formation
Jasperoid is a rare and peculiar type of metasomatic alteration of rocks. It is formed by extreme alteration of wall rocks within a shear zone which may occur in sediments, andesites, trachytes and basalts.
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.

More about Jasperoid and Lignite
Here you can know more about Jasperoid and Lignite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Jasperoid and Lignite consists of mineral content and compound content. The mineral content of Jasperoid includes Clay Minerals, Pyrite, Quartz, Sulfides and mineral content of Lignite includes . You can also check out the list of all Sedimentary Rocks. When we have to compare Jasperoid vs Lignite, the texture, color and appearance plays an important role in determining the type of rock. Jasperoid is available in black, brown, green, grey, pink, white colors whereas, Lignite is available in black, brown, dark brown, grey, light to dark grey colors. Appearance of Jasperoid is Glassy or Pearly and that of Lignite is Veined or Pebbled. Properties of rock is another aspect for Jasperoid vs Lignite. The hardness of Jasperoid is 3.5-4 and that of Lignite is 1. The types of Jasperoid are - 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 Jasperoid is white while that of Lignite is black. The specific heat capacity of Jasperoid is 0.92 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.Jasperoid is heat resistant, pressure resistant, wear resistant whereas Lignite is heat resistant.
