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.

Diatomite rock formed from the skeletal remains of single celled plants called diatoms. When diatoms die, their skeletal remains sink to the bottom of lakes and oceans etc. hence forming diatomite deposit.

Tachylite vs Diatomite 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 Diatomite Reserves. Tachylite is a vitreous form of basaltic volcanic glass. This glass is formed naturally by the rapid cooling of molten basalt. Diatomite is a fine-grained sedimentary rock which is formed from consolidated diatomaceous earth. 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 Diatomite information and Tachylite vs Diatomite characteristics in the upcoming sections.

More about Tachylite and Diatomite

Here you can know more about Tachylite and Diatomite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Tachylite and Diatomite consists of mineral content and compound content. The mineral content of Tachylite includes Feldspar, Olivine and mineral content of Diatomite includes Calcite, Clay, Clay Minerals, Quartz, Sand. You can also check out the list of all Igneous Rocks. When we have to compare Tachylite vs Diatomite, the texture, color and appearance plays an important role in determining the type of rock. Tachylite is available in black, dark brown colors whereas, Diatomite is available in grey, white, yellow colors. Appearance of Tachylite is Glassy and that of Diatomite is Soft. Properties of rock is another aspect for Tachylite vs Diatomite. The hardness of Tachylite is 5.5 and that of Diatomite is 1. The types of Tachylite are Volcanic glass whereas types of Diatomite are Diatomite. 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 Diatomite is white. The specific heat capacity of Tachylite is 0.56 kJ/Kg K and that of Diatomite is 0.90 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 Diatomite is heat resistant.
