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.

Marble is a metamorphic rock produced from limestone in the earth crust. It is formed by the metamorphism of limestone.

Anthracite vs Marble Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Anthracite and Marble Reserves. Anthracite is a type of sedimentary rock which is hard and is variety of coal that has high luster. Marble is a non-foliated metamorphic rock which is composed of recrystallized carbonate which is formed when limestone is exposed to high temperatures and pressures over a long time. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Anthracite vs Marble information and Anthracite vs Marble characteristics in the upcoming sections.

More about Anthracite and Marble

Here you can know more about Anthracite and Marble. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Anthracite and Marble consists of mineral content and compound content. The mineral content of Anthracite includes Calcite, Clay, Clay Minerals and mineral content of Marble includes Garnet, Graphite, Olivine, Pyrite, Quartz. You can also check out the list of all Metamorphic Rocks. When we have to compare Anthracite vs Marble, 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, Marble is available in black, blue, brown, grey, pink, white colors. Appearance of Anthracite is Veined or Pebbled and that of Marble is Veined and Shiny. Properties of rock is another aspect for Anthracite vs Marble. The hardness of Anthracite is 1-1.5 and that of Marble is 3-4. The types of Anthracite are Semi-anthracite and Meta-anthracite whereas types of Marble are Breccia Marble, Carrara Marble, Calacatta marble, Cultured Marble, Polished Marble, Honed Marble, Sand Marble. 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 Marble is white. The specific heat capacity of Anthracite is 1.32 kJ/Kg K and that of Marble is 0.88 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 Marble is heat resistant.
