Definition
Diamictite is a sedimentary rock that consists of non-sorted to poorly sorted terrigenous sediment containing particles that range in size from clay to boulders, suspended in a matrix of mudstone or sandstone
Lignite is a soft brownish coal which shows traces of plants and is intermediate between bituminous coal and peat

Archaeological Significance
Formation
Diamictite is unevenly sorted terrigenous, non-calcareous sedimentary rock which forms due to weathering of mudstone and sandstone.
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.

Diamictite 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. Diamictite vs Lignite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Diamictite and Properties of Lignite. Learn more about Diamictite vs Lignite in the next section. The interior uses of Diamictite include Decorative aggregates and Interior decoration whereas the interior uses of Lignite include . Due to some exceptional properties of Diamictite and Lignite, they have various applications in construction industry. The uses of Diamictite in construction industry include As dimension stone, Construction aggregate, For road aggregate, Landscaping, Roadstone and that of Lignite include For road aggregate, Steel production.
More about Diamictite and Lignite
Here you can know more about Diamictite and Lignite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Diamictite and Lignite consists of mineral content and compound content. The mineral content of Diamictite includes Calcite, Clay, Feldspar, Micas, Quartz and mineral content of Lignite includes . You can also check out the list of all Sedimentary Rocks. When we have to compare Diamictite vs Lignite, the texture, color and appearance plays an important role in determining the type of rock. Diamictite is available in brown, buff colors whereas, Lignite is available in black, brown, dark brown, grey, light to dark grey colors. Appearance of Diamictite is Banded and that of Lignite is Veined or Pebbled. Properties of rock is another aspect for Diamictite vs Lignite. The hardness of Diamictite is 2-3 and that of Lignite is 1. The types of Diamictite are Bedded Diamictite and Laminated Diamictite 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 Diamictite is light to dark brown while that of Lignite is black. The specific heat capacity of Diamictite is 0.75 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.Diamictite is heat resistant, impact resistant whereas Lignite is heat resistant.
