Definition
During the impact melted material forming a breccia containing glass and crystal or lithic fragments together form Suevite rock.

Archaeological Significance
Formation
Suevite is a metamorphic rock consisting partly of melted material, typically forming a breccia containing glass and crystal or lithic fragments, formed during an impact event.
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.

All about Suevite and Pseudotachylite Properties
Know all about Suevite and Pseudotachylite properties here. All properties of rocks are important as they define the type of rock and its application. Suevite and Pseudotachylite belong to Metamorphic Rocks.Texture of Suevite is Earthy whereas that of Pseudotachylite is Quench. Suevite appears Banded and Pseudotachylite appears Dull and Soft. The luster of Suevite is earthy while that of Pseudotachylite is vitreous. Suevite is available in black, brown, green, grey, pink colors whereas Pseudotachylite is available in black, brown, green, grey, pink, white colors. The commercial uses of Suevite are as a feed additive for livestock, gemstone, metallurgical flux, source of magnesia (mgo) and that of Pseudotachylite are creating artwork, gemstone.
