Definition
A sedimentary rock, deposit of a submarine turbidity currents and are composed of layered particles
Very fine grained fault rock which is composed of glassy matrix that often contains inclusions of wall-rock fragments.
Origin
European Foreland Basins

Etymology
From Medieval Latin turbiditas, from Latin turbidus (turbid). Turbidity current is from 1939
From pseudo- + tachylite, a glassy rock generated by frictional heat within faults.

Formation
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.
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Pseudotachylite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

Turbidite vs Pseudotachylite 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. Turbidite vs Pseudotachylite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Turbidite and Properties of Pseudotachylite. Learn more about Turbidite vs Pseudotachylite in the next section. The interior uses of Turbidite include Bathrooms, Countertops, Decorative aggregates, Flooring, Homes and Interior decoration whereas the interior uses of Pseudotachylite include Decorative aggregates, Entryways and Interior decoration. Due to some exceptional properties of Turbidite and Pseudotachylite, they have various applications in construction industry. The uses of Turbidite in construction industry include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Making natural cement and that of Pseudotachylite include As dimension stone, Cement manufacture, For road aggregate, Making natural cement.
More about Turbidite and Pseudotachylite
Here you can know more about Turbidite and Pseudotachylite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Turbidite and Pseudotachylite consists of mineral content and compound content. The mineral content of Turbidite includes Coesite, Quartz, Sand and mineral content of Pseudotachylite includes Iron Oxides, Pyroxene, Quartz, Stishovite, Sulfides. You can also check out the list of all Sedimentary Rocks. When we have to compare Turbidite vs Pseudotachylite, the texture, color and appearance plays an important role in determining the type of rock. Turbidite is available in black, brown, colourless, green, grey, pink colors whereas, Pseudotachylite is available in black, brown, colourless, green, grey, pink, white colors. Appearance of Turbidite is Dull and Banded and that of Pseudotachylite is Dull and Soft. Properties of rock is another aspect for Turbidite vs Pseudotachylite. The hardness of Turbidite is 3 and that of Pseudotachylite is 7. The types of Turbidite are Not Available whereas types of Pseudotachylite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Turbidite is white, greenish white or grey while that of Pseudotachylite is light to dark brown. The specific heat capacity of Turbidite is 0.92 kJ/Kg K and that of Pseudotachylite 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.Turbidite is heat resistant whereas Pseudotachylite is heat resistant.
