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.
Coal formation takes place due to accumulation of plant debris in a swamp environment. The Coal formation process continues, as peat turns into lignite brown or black coal at increasing heat and pressure.

Tachylite vs Lignite 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 Lignite Reserves. Tachylite is a vitreous form of basaltic volcanic glass. This glass is formed naturally by the rapid cooling of molten basalt. Lignite is a soft brownish coal which shows traces of plants and is intermediate between bituminous coal and peat. 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 Tachylite vs Lignite information and Tachylite vs Lignite characteristics in the upcoming sections.

Tachylite vs Lignite Characteristics

Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Tachylite vs Lignite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Tachylite and Properties of Lignite. Learn more about Tachylite vs Lignite in the next section. The interior uses of Tachylite include Decorative aggregates and Interior decoration whereas the interior uses of Lignite include Not yet used. Due to some exceptional properties of Tachylite and Lignite, they have various applications in construction industry. The uses of Tachylite in construction industry include Cutting tool, Knives, Landscaping, Scrapers and that of Lignite include For road aggregate, Steel production.

More about Tachylite and Lignite

Here you can know more about Tachylite and Lignite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Tachylite and Lignite consists of mineral content and compound content. The mineral content of Tachylite includes Feldspar, Olivine and mineral content of Lignite is not available. You can also check out the list of all . When we have to compare Tachylite vs Lignite, the texture, color and appearance plays an important role in determining the type of rock. Tachylite is available in black, dark brown colors whereas, Lignite is available in black, brown, dark brown, grey, light to dark grey colors. Appearance of Tachylite is Glassy and that of Lignite is Veined or Pebbled. Properties of rock is another aspect for Tachylite vs Lignite. The hardness of Tachylite is 5.5 and that of Lignite is 1. The types of Tachylite are Not Available whereas types of Lignite are Xyloid Lignite or Fossil Wood and Compact Lignite or Perfect Lignite. 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 Lignite is black. The specific heat capacity of Tachylite is 0.56 kJ/Kg K and that of Lignite 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.Tachylite is heat resistant, impact resistant, wear resistant whereas Lignite is heat resistant.
