Formation
Conglomerate forms where sediments consisting mainly of pebble and cobble-size clasts at least two millimeters in diameter starts accumulating.
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 Conglomerate and Anthracite Properties
Know all about Conglomerate and Anthracite properties here. All properties of rocks are important as they define the type of rock and its application. Conglomerate belongs to Sedimentary Rocks while Anthracite belongs to Metamorphic Rocks.Texture of Conglomerate is Clastic whereas that of Anthracite is Amorphous, Glassy. Conglomerate appears Shiny and Rounded and Anthracite appears Veined or Pebbled. The luster of Conglomerate is dull while that of Anthracite is shiny. Conglomerate is available in beige, black, brown, buff, light to dark grey, orange, rust, white, yellow colors whereas Anthracite is available in black, brown, dark brown, grey, light to dark grey colors. The commercial uses of Conglomerate are cemetery markers, in aquifers, tombstones and that of Anthracite are alumina refineries, electricity generation, liquid fuel, manufacture of soap, solvents, dyes, plastics and fibres, paper industry.
