Very fine grained fault rock which is composed of glassy matrix that often contains inclusions of wall-rock fragments.
From pseudo- + tachylite, a glassy rock generated by frictional heat within faults.

Archaeological Significance
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.
