5 Formation

5.1 Formation

Tachylite 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 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.

Tachylite vs Anthracite 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 Tachylite and Anthracite Reserves. Tachylite is a vitreous form of basaltic volcanic glass. This glass is formed naturally by the rapid cooling of molten basalt. Anthracite is a type of sedimentary rock which is hard and is variety of coal that has high luster. 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 Tachylite and Anthracite

Here you can know more about Tachylite and Anthracite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Tachylite and Anthracite consists of mineral content and compound content. The mineral content of Tachylite includes Feldspar, Olivine and mineral content of Anthracite includes Calcite, Clay, Clay Minerals. You can also check out the list of all Igneous Rocks. When we have to compare Tachylite vs Anthracite, the texture, color and appearance plays an important role in determining the type of rock. Tachylite is available in black, dark brown colors whereas, Anthracite is available in black, brown, dark brown, grey, light to dark grey colors. Appearance of Tachylite is Glassy and that of Anthracite is Veined or Pebbled. Properties of rock is another aspect for Tachylite vs Anthracite. The hardness of Tachylite is 5.5 and that of Anthracite is 1-1.5. The types of Tachylite are Not Available whereas types of Anthracite are Semi-anthracite and Meta-anthracite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Tachylite is vermilion while that of Anthracite is black. The specific heat capacity of Tachylite is 0.56 kJ/Kg K and that of Anthracite is 1.32 kJ/Kg K.
