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.

Conglomerate vs Anthracite 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. Conglomerate vs Anthracite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Conglomerate and Properties of Anthracite. Learn more about Conglomerate vs Anthracite in the next section. The interior uses of Conglomerate include Decorative aggregates, Floor tiles and Homes whereas the interior uses of Anthracite include Not yet used. Due to some exceptional properties of Conglomerate and Anthracite, they have various applications in construction industry. The uses of Conglomerate in construction industry include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Roadstone and that of Anthracite include Cement manufacture, For road aggregate, Making natural cement, Steel production.
More about Conglomerate and Anthracite
Here you can know more about Conglomerate and Anthracite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Conglomerate and Anthracite consists of mineral content and compound content. The mineral content of Conglomerate includes Clay, Sand, Silica, Silt and mineral content of Anthracite includes Calcite, Clay, Clay Minerals. You can also check out the list of all Sedimentary Rocks. When we have to compare Conglomerate vs Anthracite, the texture, color and appearance plays an important role in determining the type of rock. 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. Appearance of Conglomerate is Shiny and Rounded and that of Anthracite is Veined or Pebbled. Properties of rock is another aspect for Conglomerate vs Anthracite. The hardness of Conglomerate is 2-3 and that of Anthracite is 1-1.5. The types of Conglomerate are Not Available whereas types of Anthracite are Semi-anthracite and Meta-anthracite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Conglomerate is white while that of Anthracite is black. The specific heat capacity of Conglomerate is 0.92 kJ/Kg K and that of Anthracite is 1.32 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Conglomerate is heat resistant whereas Anthracite is heat resistant, water resistant.
