Definition
Very fine grained fault rock which is composed of glassy matrix that often contains inclusions of wall-rock fragments.
Pantellerite is a peralkaline rhyolite. It has a higher iron and lower aluminium composition than comendite

Formation
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.
Pantellerite 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.

All about Pseudotachylite and Pantellerite Properties
Know all about Pseudotachylite and Pantellerite properties here. All properties of rocks are important as they define the type of rock and its application. Pseudotachylite belongs to Metamorphic Rocks while Pantellerite belongs to Igneous Rocks.Texture of Pseudotachylite is Quench whereas that of Pantellerite is Eutaxitic. Pseudotachylite appears Dull and Soft and Pantellerite appears Layered and Foliated. The luster of Pseudotachylite is vitreous while that of Pantellerite is earthy. Pseudotachylite is available in black, brown, colourless, green, grey, pink, white colors whereas Pantellerite is available in dark greenish - grey colors. The commercial uses of Pseudotachylite and Pantellerite are creating artwork, gemstone.
