1 Definition
1.1 Definition
Coal is a combustible black or brownish-black sedimentary rock usually occurring in rock strata in layers called coal beds
Tachylite is a vitreous form of basaltic volcanic glass. This glass is formed naturally by the rapid cooling of molten basalt

5 Formation
5.1 Formation
Coal forms from the accumulation of plant debris in a swamp environment which is buried by sediments such as mud or sand and then compacted to form coal.
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 vs Tachylite 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 Coal and Tachylite Reserves. Coal is a combustible black or brownish-black sedimentary rock usually occurring in rock strata in layers called coal beds. Tachylite is a vitreous form of basaltic volcanic glass. This glass is formed naturally by the rapid cooling of molten basalt. 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 Coal vs Tachylite information and Coal vs Tachylite characteristics in the upcoming sections.

Coal vs Tachylite 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. Coal vs Tachylite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Coal and Properties of Tachylite. Learn more about Coal vs Tachylite in the next section. The interior uses of Coal include Not yet used whereas the interior uses of Tachylite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Coal and Tachylite, they have various applications in construction industry. The uses of Coal in construction industry include Cement manufacture, For road aggregate, Making natural cement, Steel production and that of Tachylite include Cutting tool, Knives, Landscaping, Scrapers.

More about Coal and Tachylite

Here you can know more about Coal and Tachylite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Coal and Tachylite consists of mineral content and compound content. The mineral content of Coal includes Analcime, Apatite, Barite, Calcite, Chalcopyrite, Chlorite, Chromite, Clausthalite, Clay Minerals, Crandallite Group, Dolomite, Feldspar, Galena, Gypsum, Marcasite, Muscovite or Illite, Pyrite, Quartz, Siderite, Sphalerite, Zircon and mineral content of Tachylite includes Feldspar, Olivine. You can also check out the list of all Sedimentary Rocks. When we have to compare Coal vs Tachylite, the texture, color and appearance plays an important role in determining the type of rock. Coal is available in black, brown, dark brown, grey, light to dark grey colors whereas, Tachylite is available in black, dark brown colors. Appearance of Coal is Veined or Pebbled and that of Tachylite is Glassy. Properties of rock is another aspect for Coal vs Tachylite. The hardness of Coal is 1-1.5 and that of Tachylite is 5.5. The types of Coal are Peat, Lignite, Sub-Bituminous Coal, Bituminous Coal, Anthracite, Graphite whereas types of Tachylite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Coal is black while that of Tachylite is vermilion. The specific heat capacity of Coal is 1.32 kJ/Kg K and that of Tachylite is 0.56 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Coal is heat resistant whereas Tachylite is heat resistant, impact resistant, wear resistant.
