Definition
Oolite is a sedimentary rock formed from ooids, spherical grains which are composed of concentric layers of calcite
Lignite is a soft brownish coal which shows traces of plants and is intermediate between bituminous coal and peat

Formation
Oolites form when layers of calcite are deposited around a sand grain or fossil piece and are rolled around in calm water, which makes them round.
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.

Oolite 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. Oolite vs Lignite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Oolite and Properties of Lignite. Learn more about Oolite vs Lignite in the next section. The interior uses of Oolite include Decorative aggregates, Flooring and Interior decoration whereas the interior uses of Lignite include Not yet used. Due to some exceptional properties of Oolite and Lignite, they have various applications in construction industry. The uses of Oolite in construction industry include Cement manufacture, Cobblestones, Landscaping and that of Lignite include For road aggregate, Steel production.
More about Oolite and Lignite
Here you can know more about Oolite and Lignite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Oolite and Lignite consists of mineral content and compound content. The mineral content of Oolite includes Calcite, Chert, Clay, Dolomite, Quartz, Sand, Silt and mineral content of Lignite is not available. You can also check out the list of all Sedimentary Rocks. When we have to compare Oolite vs Lignite, the texture, color and appearance plays an important role in determining the type of rock. Oolite is available in black, blue, brown, cream, green, grey, pink, red, silver, white, yellow colors whereas, Lignite is available in black, brown, dark brown, grey, light to dark grey colors. Appearance of Oolite is Rounded and Rough and that of Lignite is Veined or Pebbled. Properties of rock is another aspect for Oolite vs Lignite. The hardness of Oolite is 3-4 and that of Lignite is 1. The types of Oolite are Not Available 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 Oolite is white while that of Lignite is black. The specific heat capacity of Oolite is Not Available 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.Oolite is heat resistant, wear resistant whereas Lignite is heat resistant.
