Definition
A ganister is a hard, fine-grained quartzose sandstone or orthoquartzite which is basically used in the manufacture of silica brick typically used to line furnaces and is a type of sedimentary rocks.
Anthracite is a type of sedimentary rock which is hard and is variety of coal that has high luster

Formation
Ganisters are formed by the destruction of easily weathered minerals mainly feldspar, within the surface horizon of soil by soil-forming processes.
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.

All about Ganister and Anthracite Properties
Know all about Ganister and Anthracite properties here. All properties of rocks are important as they define the type of rock and its application. Ganister belongs to Sedimentary Rocks while Anthracite belongs to Metamorphic Rocks.Texture of Ganister is Clastic, Granular, Rough whereas that of Anthracite is Amorphous, Glassy. Ganister appears Rough and Anthracite appears Veined or Pebbled. The luster of Ganister is dull while that of Anthracite is shiny. Ganister and Anthracite are available in beige, black, brown, colourless, cream, dark brown, green, grey, light green, light to dark grey, pink, red, white, yellow colors. The commercial uses of Ganister are an oil and gas reservoir, in aquifers, petroleum reservoirs, soil conditioner, source of magnesia (mgo), tombstones and that of Anthracite are alumina refineries, electricity generation, liquid fuel, manufacture of soap, solvents, dyes, plastics and fibres, paper industry.
