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.

Shale forms when very fine-grained clay particles are deposited in water which settle at the bottom of water bodies. They are later compacted hence forming shale.

Tachylite vs Shale 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 Shale Reserves. Tachylite is a vitreous form of basaltic volcanic glass. This glass is formed naturally by the rapid cooling of molten basalt. Shale is a fine-grained sedimentary rock which is formed by the compaction of silt and clay-size mineral particles. 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 Shale information and Tachylite vs Shale characteristics in the upcoming sections.

Tachylite vs Shale 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 Shale characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Tachylite and Properties of Shale. Learn more about Tachylite vs Shale in the next section. The interior uses of Tachylite include Decorative aggregates and Interior decoration whereas the interior uses of Shale include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Tachylite and Shale, they have various applications in construction industry. The uses of Tachylite in construction industry include Cutting tool, Knives, Landscaping, Scrapers and that of Shale include Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for the manufacture of mortar.

More about Tachylite and Shale

Here you can know more about Tachylite and Shale. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Tachylite and Shale consists of mineral content and compound content. The mineral content of Tachylite includes Feldspar, Olivine and mineral content of Shale includes Albite, Biotite, Calcite, Chert, Chlorite, Dolomite, Hematite, Micas, Muscovite or Illite, Pyrite, Quartz, Silica, Sulfides. You can also check out the list of all Igneous Rocks. When we have to compare Tachylite vs Shale, the texture, color and appearance plays an important role in determining the type of rock. Tachylite is available in black, dark brown colors whereas, Shale is available in black, brown, buff, green, grey, red, yellow colors. Appearance of Tachylite is Glassy and that of Shale is Muddy. Properties of rock is another aspect for Tachylite vs Shale. The hardness of Tachylite is 5.5 and that of Shale is 3. The types of Tachylite are Not Available whereas types of Shale are Red Shale, Black Shale, Green Shale, Grey Shale and Yellow Shale. 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 Shale is white. The specific heat capacity of Tachylite is 0.56 kJ/Kg K and that of Shale is 0.39 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 Shale is heat resistant, impact resistant.
