Definition
Very fine grained fault rock which is composed of glassy matrix that often contains inclusions of wall-rock fragments.
Marble is a non-foliated metamorphic rock which is composed of recrystallized carbonate which is formed when limestone is exposed to high temperatures and pressures over a long time

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.
Marble is a metamorphic rock produced from limestone in the earth crust. It is formed by the metamorphism of limestone.

All about Pseudotachylite and Marble Properties
Know all about Pseudotachylite and Marble properties here. All properties of rocks are important as they define the type of rock and its application. Pseudotachylite and Marble belong to Metamorphic Rocks.Texture of Pseudotachylite is Quench whereas that of Marble is Granular. Pseudotachylite appears Dull and Soft and Marble appears Veined and Shiny. The luster of Pseudotachylite is vitreous while that of Marble is dull to pearly to subvitreous. Pseudotachylite is available in black, brown, colourless, green, grey, pink, white colors whereas Marble is available in black, blue, brown, grey, pink, white colors. The commercial uses of Pseudotachylite are creating artwork, gemstone and that of Marble are cemetery markers, commemorative tablets, creating artwork, curling, laboratory bench tops, paper industry, tombstones, used in aquariums, whiting material in toothpaste, paint and paper.
