Definition
Tachylite is a vitreous form of basaltic volcanic glass. This glass is formed naturally by the rapid cooling of molten basalt
A sedimentary rock, deposit of a submarine turbidity currents and are composed of layered particles
Origin

Etymology
From German Tachylite, from tachy- + Greek lutos soluble, melting
From Medieval Latin turbiditas, from Latin turbidus (turbid). Turbidity current is from 1939

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.
Turbidite is a type of sedimentary rock formed when a river carries or transports pieces of broken rock as it flows. These particles then settle down and are subjected to high temperature and pressures hence forming Turbidite.

More about Tachylite and Turbidite
Here you can know more about Tachylite and Turbidite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Tachylite and Turbidite consists of mineral content and compound content. The mineral content of Tachylite includes Feldspar, Olivine and mineral content of Turbidite includes Coesite, Quartz, Sand. You can also check out the list of all . When we have to compare Tachylite vs Turbidite, the texture, color and appearance plays an important role in determining the type of rock. Tachylite is available in black, dark brown colors whereas, Turbidite is available in black, brown, colourless, green, grey, pink colors. Appearance of Tachylite is Glassy and that of Turbidite is Dull and Banded. Properties of rock is another aspect for Tachylite vs Turbidite. The hardness of Tachylite is 5.5 and that of Turbidite is 3. The types of Tachylite are Not Available whereas types of Turbidite are Not Available. 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 Turbidite is white, greenish white or grey. The specific heat capacity of Tachylite is 0.56 kJ/Kg K and that of Turbidite is 0.92 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 Turbidite is heat resistant.
