Definition
Very fine grained fault rock which is composed of glassy matrix that often contains inclusions of wall-rock fragments.
Monzogranite is a type of igneous rock and belongs to biotite granite rocks that are considered to be the final fractionation product of magma

Archaeological Significance
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.
Monzogranite 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 Monzogranite Properties
Know all about Pseudotachylite and Monzogranite properties here. All properties of rocks are important as they define the type of rock and its application. Pseudotachylite belongs to Metamorphic Rocks while Monzogranite belongs to Igneous Rocks.Texture of Pseudotachylite is Quench whereas that of Monzogranite is Porphyritic. Pseudotachylite appears Dull and Soft and Monzogranite appears Veined or Pebbled. The luster of Pseudotachylite is vitreous while that of Monzogranite is dull to grainy with sporadic parts pearly and vitreous. Pseudotachylite is available in black, brown, green, grey, pink, white colors whereas Monzogranite is available in black, grey, orange, pink, white colors. The commercial uses of Pseudotachylite are creating artwork, gemstone and that of Monzogranite are cemetery markers, commemorative tablets, creating artwork, curling, tombstones.
