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

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.

All about Turbidite and Pseudotachylite Properties
Know all about Turbidite and Pseudotachylite properties here. All properties of rocks are important as they define the type of rock and its application. Turbidite belongs to Sedimentary Rocks while Pseudotachylite belongs to Metamorphic Rocks.Texture of Turbidite is Mud-rich, Sandy whereas that of Pseudotachylite is Quench. Turbidite appears Dull and Banded and Pseudotachylite appears Dull and Soft. The luster of Turbidite is metallic while that of Pseudotachylite is vitreous. Turbidite is available in black, brown, colourless, green, grey, pink colors whereas Pseudotachylite is available in black, brown, colourless, green, grey, pink, white colors. The commercial uses of Turbidite are cemetery markers, creating artwork and that of Pseudotachylite are creating artwork, gemstone.
