Definition
During the impact melted material forming a breccia containing glass and crystal or lithic fragments together form Suevite rock.
Tachylite is a vitreous form of basaltic volcanic glass. This glass is formed naturally by the rapid cooling of molten basalt

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.
Tachylite 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 Suevite and Tachylite Properties
Know all about Suevite and Tachylite properties here. All properties of rocks are important as they define the type of rock and its application. Suevite belongs to Metamorphic Rocks while Tachylite belongs to Igneous Rocks.Texture of Suevite is Earthy whereas that of Tachylite is Vitreous. Suevite appears Banded and Tachylite appears Glassy. The luster of Suevite is earthy while that of Tachylite is resinous. Suevite is available in black, brown, colourless, green, grey, pink colors whereas Tachylite is available in black, dark brown colors. The commercial uses of Suevite are as a feed additive for livestock, gemstone, metallurgical flux, source of magnesia (mgo) and that of Tachylite are cemetery markers, creating artwork.
