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.
