Definition
Lignite is a soft brownish coal which shows traces of plants and is intermediate between bituminous coal and peat
Marble is a non-foliated metamorphic rock which is composed of recrystallized carbonate which is formed when limestone is exposed to high temperatures and pressures over a long time

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.
Marble is a metamorphic rock produced from limestone in the earth crust. It is formed by the metamorphism of limestone.

Lignite vs Marble 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 Marble characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Lignite and Properties of Marble. Learn more about Lignite vs Marble in the next section. The interior uses of Lignite include whereas the interior uses of Marble include Bathrooms, Countertops, Decorative aggregates, Entryways, Floor tiles, Homes, Hotels, Interior decoration, Kitchens and Stair treads. Due to some exceptional properties of Lignite and Marble, they have various applications in construction industry. The uses of Lignite in construction industry include For road aggregate, Steel production and that of Marble include As dimension stone.
More about Lignite and Marble
Here you can know more about Lignite and Marble. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Lignite and Marble consists of mineral content and compound content. The mineral content of Lignite includes and mineral content of Marble includes Garnet, Graphite, Olivine, Pyrite, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Lignite vs Marble, 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, Marble is available in black, blue, brown, grey, pink, white colors. Appearance of Lignite is Veined or Pebbled and that of Marble is Veined and Shiny. Properties of rock is another aspect for Lignite vs Marble. The hardness of Lignite is 1 and that of Marble is 3-4. The types of Lignite are Xyloid Lignite or Fossil Wood and Compact Lignite or Perfect Lignite whereas types of Marble are Breccia Marble, Carrara Marble, Calacatta marble, Cultured Marble, Polished Marble, Honed Marble, Sand Marble. 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 Marble is white. The specific heat capacity of Lignite is 1.26 kJ/Kg K and that of Marble is 0.88 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 Marble is heat resistant.
