1.3 Etymology

From Greek anthrakites, from anthrax, anthrak meaning coal

From the Lherz Massif, an alpine peridotite complex, at Étang de Lers, near Massat in the French Pyrenees; Lherz is the archaic spelling of this location

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.

Lherzolite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

Anthracite vs Lherzolite 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 Lherzolite Reserves. Anthracite is a type of sedimentary rock which is hard and is variety of coal that has high luster. Lherzolite is a type of ultramafic igneous rock which contains essential olivine and clinopyroxene and orthopyroxene in equal proportions. 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 Lherzolite information and Anthracite vs Lherzolite characteristics in the upcoming sections.

More about Anthracite and Lherzolite

Here you can know more about Anthracite and Lherzolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Anthracite and Lherzolite consists of mineral content and compound content. The mineral content of Anthracite includes Calcite, Clay, Clay Minerals and mineral content of Lherzolite includes Harzburgite, Olivine, Pyroxene, Pyrrhotite. You can also check out the list of all Metamorphic Rocks. When we have to compare Anthracite vs Lherzolite, 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, Lherzolite is available in black, dark greenish - grey, green, pink, purple colors. Appearance of Anthracite is Veined or Pebbled and that of Lherzolite is Glassy, Vesicular and Foilated. Properties of rock is another aspect for Anthracite vs Lherzolite. The hardness of Anthracite is 1-1.5 and that of Lherzolite is 6.5. The types of Anthracite are Semi-anthracite and Meta-anthracite whereas types of Lherzolite are Garnet Lherzolite. 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 Lherzolite is white. The specific heat capacity of Anthracite is 1.32 kJ/Kg K and that of Lherzolite is 0.95 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 Lherzolite is heat resistant, impact resistant, pressure resistant, wear resistant.
