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.
Conglomerate forms where sediments consisting mainly of pebble and cobble-size clasts at least two millimeters in diameter starts accumulating.

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