5 Formation
5.1 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.
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.

All about Suevite and Tephrite Properties

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