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.
Limestone is a sedimentary rock which is mainly made up of calcium carbonate.

All about Anthracite and Limestone Properties
Know all about Anthracite and Limestone properties here. All properties of rocks are important as they define the type of rock and its application. Anthracite belongs to Metamorphic Rocks while Limestone belongs to Sedimentary Rocks.Texture of Anthracite is Amorphous, Glassy whereas that of Limestone is Clastic or Non-Clastic. Anthracite appears Veined or Pebbled and Limestone appears Rough and Banded. The luster of Anthracite is shiny while that of Limestone is dull to pearly. Anthracite is available in black, brown, dark brown, grey, light to dark grey colors whereas Limestone is available in beige, black, blue, brown, cream, gold, green, grey, light green, light grey, linen, pink, red, rust, 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 Limestone are animal feed filler, as a feed additive for livestock, paper industry, raw material for manufacture of quicklime, slaked lime, soil conditioner, used in aquariums, whiting material in toothpaste, paint and paper.
