Definition
Lignite is a soft brownish coal which shows traces of plants and is intermediate between bituminous coal and peat
Conglomerate is a sedimentary rock which forms from rounded gravel and boulder sized clasts which are cemented together in a matrix

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.
Conglomerate forms where sediments consisting mainly of pebble and cobble-size clasts at least two millimeters in diameter starts accumulating.

Lignite vs Conglomerate 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. Lignite vs Conglomerate characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Lignite and Properties of Conglomerate. Learn more about Lignite vs Conglomerate in the next section. The interior uses of Lignite include Not yet used whereas the interior uses of Conglomerate include Decorative aggregates, Floor tiles and Homes. Due to some exceptional properties of Lignite and Conglomerate, they have various applications in construction industry. The uses of Lignite in construction industry include For road aggregate, Steel production and that of Conglomerate include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Roadstone.
More about Lignite and Conglomerate
Here you can know more about Lignite and Conglomerate. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Lignite and Conglomerate consists of mineral content and compound content. The mineral content of Lignite is not available and mineral content of Conglomerate includes Clay, Sand, Silica, Silt. You can also check out the list of all Sedimentary Rocks. When we have to compare Lignite vs Conglomerate, 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, Conglomerate is available in beige, black, brown, buff, light to dark grey, orange, rust, white, yellow colors. Appearance of Lignite is Veined or Pebbled and that of Conglomerate is Shiny and Rounded. Properties of rock is another aspect for Lignite vs Conglomerate. The hardness of Lignite is 1 and that of Conglomerate is 2-3. The types of Lignite are Xyloid Lignite or Fossil Wood and Compact Lignite or Perfect Lignite whereas types of Conglomerate are Not Available. 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 Conglomerate is white. The specific heat capacity of Lignite is 1.26 kJ/Kg K and that of Conglomerate is 0.92 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 Conglomerate is heat resistant.
