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.

When alkali feldspar is extracted from granite, it changes to granitoid and later, it becomes tonalite with quartz as major mineral.

Anthracite vs Tonalite 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 Tonalite Reserves. Anthracite is a type of sedimentary rock which is hard and is variety of coal that has high luster. Tonalite is a coarse-grained plutonic rock consisting mainly of sodic plagioclase, quartz, and hornblende or other mafic minerals with phaneritic texture. 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.

More about Anthracite and Tonalite

Here you can know more about Anthracite and Tonalite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Anthracite and Tonalite consists of mineral content and compound content. The mineral content of Anthracite includes Calcite, Clay, Clay Minerals and mineral content of Tonalite includes Albite, Amphibole, Apatite, Biotite, Feldspar, Hornblade, Ilmenite, Magnetite, Manganese Oxides, Olivine, Plagioclase, Pyroxene, Quartz, Sulfides, Titanite, Zircon. You can also check out the list of all Metamorphic Rocks. When we have to compare Anthracite vs Tonalite, 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, Tonalite is available in black, brown, light to dark grey, white colors. Appearance of Anthracite is Veined or Pebbled and that of Tonalite is Banded and Foilated. Properties of rock is another aspect for Anthracite vs Tonalite. The hardness of Anthracite is 1-1.5 and that of Tonalite is 6-7. The types of Anthracite are Semi-anthracite and Meta-anthracite whereas types of Tonalite are Dacite. 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 Tonalite is bluish black. The specific heat capacity of Anthracite is 1.32 kJ/Kg K and that of Tonalite 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 Tonalite is heat resistant, pressure resistant, water resistant.
