Formation
Anthracite forms from the accumulation of plant debris in a swamp environment. When plant debris dies and falls into the swamp, the standing water of the swamp protects it from decay.
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.

All about Anthracite and Oolite Properties
Know all about Anthracite and Oolite properties here. All properties of rocks are important as they define the type of rock and its application. Anthracite belongs to Metamorphic Rocks while Oolite belongs to Sedimentary Rocks.Texture of Anthracite is Amorphous, Glassy whereas that of Oolite is Clastic or Non-Clastic. Anthracite appears Veined or Pebbled and Oolite appears Rounded and Rough. The luster of Anthracite is shiny while that of Oolite is pearly to shiny. Anthracite is available in black, brown, dark brown, grey, light to dark grey colors whereas Oolite is available in black, blue, brown, cream, green, grey, pink, red, silver, white, yellow colors. The commercial uses of Anthracite are alumina refineries, electricity generation, liquid fuel, manufacture of soap, solvents, dyes, plastics and fibres, paper industry and that of Oolite are creating artwork, jewelry, used in aquariums.
