Definition
Cataclasite is a type of cataclastic rock that is formed by fracturing and comminution during faulting. It is normally cohesive and non-foliated, consisting of angular clasts in a finer-grained matrix
Lignite is a soft brownish coal which shows traces of plants and is intermediate between bituminous coal and peat

Archaeological Significance
Formation
Cataclasiste rocks mainly form by pressure deep under the Earth's surface, from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.
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.

Cataclasite 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. Cataclasite vs Lignite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Cataclasite and Properties of Lignite. Learn more about Cataclasite vs Lignite in the next section. The interior uses of Cataclasite include Decorative aggregates and Homes whereas the interior uses of Lignite include . Due to some exceptional properties of Cataclasite and Lignite, they have various applications in construction industry. The uses of Cataclasite in construction industry include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate and that of Lignite include For road aggregate, Steel production.
More about Cataclasite and Lignite
Here you can know more about Cataclasite and Lignite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Cataclasite and Lignite consists of mineral content and compound content. The mineral content of Cataclasite includes Albite, Apatite, Augite, Biotite, Calcite, Enstatite, Epidote, Feldspar, Micas, Muscovite or Illite, Pyroxene, Quartz and mineral content of Lignite includes . You can also check out the list of all Metamorphic Rocks. When we have to compare Cataclasite vs Lignite, the texture, color and appearance plays an important role in determining the type of rock. Cataclasite is available in brown, green, white, yellow colors whereas, Lignite is available in black, brown, dark brown, grey, light to dark grey colors. Appearance of Cataclasite is Dull and Banded and that of Lignite is Veined or Pebbled. Properties of rock is another aspect for Cataclasite vs Lignite. The hardness of Cataclasite is 3-4 and that of Lignite is 1. The types of Cataclasite are Protocataclasite, Mesocataclasite, Ultracataclasite and Foliated cataclasite 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 Cataclasite and Lignite is black. The specific heat capacity of Cataclasite is 0.84 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.Cataclasite is heat resistant, impact resistant, pressure resistant whereas Lignite is heat resistant.
