1 Definition
1.1 Definition
Tephrite is an aphanitic to porphyritic textured, volcanic igneous rock
During the impact melted material forming a breccia containing glass and crystal or lithic fragments together form Suevite rock.

5 Formation
5.1 Formation
Tephrite 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.
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.

All about Tephrite and Suevite Properties

Know all about Tephrite and Suevite properties here. All properties of rocks are important as they define the type of rock and its application. Tephrite belongs to Igneous Rocks while Suevite belongs to Metamorphic Rocks.Texture of Tephrite is Aphanitic to Porphyritic whereas that of Suevite is Earthy. Tephrite appears Vesicular and Suevite appears Banded. The luster of Tephrite is subvitreous to dull while that of Suevite is earthy. Tephrite is available in black, brown, colourless, green, grey, white colors whereas Suevite is available in black, brown, colourless, green, grey, pink colors. The commercial uses of Tephrite are production of lime, soil conditioner and that of Suevite are as a feed additive for livestock, gemstone, metallurgical flux, source of magnesia (mgo).
