5 Formation

5.1 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.

Peridotites can be formed in two ways: as mantle rocks formed during the accretion and differentiation of the Earth or as cumulate rocks formed by precipitation of olivine and pyroxenes from basaltic magmas.

Anthracite vs Peridotite 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 Peridotite Reserves. Anthracite is a type of sedimentary rock which is hard and is variety of coal that has high luster. Peridotite is a dense, coarse-grained plutonic is the main constituent of the earth's mantle. 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 Peridotite information and Anthracite vs Peridotite characteristics in the upcoming sections.

More about Anthracite and Peridotite

Here you can know more about Anthracite and Peridotite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Anthracite and Peridotite consists of mineral content and compound content. The mineral content of Anthracite includes Calcite, Clay, Clay Minerals and mineral content of Peridotite includes Amphibole, Chromite, Garnet, Magnesium, Olivine, Phlogopite, Plagioclase, Pyroxene. You can also check out the list of all Metamorphic Rocks. When we have to compare Anthracite vs Peridotite, 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, Peridotite is available in dark greenish - grey colors. Appearance of Anthracite is Veined or Pebbled and that of Peridotite is Rough and Shiny. Properties of rock is another aspect for Anthracite vs Peridotite. The hardness of Anthracite is 1-1.5 and that of Peridotite is 5.5-6. The types of Anthracite are Semi-anthracite and Meta-anthracite whereas types of Peridotite are Dunite, Wehrlite, Harzburgite, Lherzolite and Pyrolite. 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 Peridotite is white. The specific heat capacity of Anthracite is 1.32 kJ/Kg K and that of Peridotite is 1.26 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 Peridotite is heat resistant, pressure resistant, wear resistant.
