5 Formation
5.1 Formation
Pyrolite 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.
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 Pyrolite and Tephrite Properties

Know all about Pyrolite and Tephrite properties here. All properties of rocks are important as they define the type of rock and its application. Pyrolite and Tephrite belong to Igneous Rocks.Texture of Pyrolite is Phaneritic whereas that of Tephrite is Aphanitic to Porphyritic. Pyrolite appears Rough and Shiny and Tephrite appears Vesicular. The luster of Pyrolite is shiny while that of Tephrite is subvitreous to dull. Pyrolite is available in dark greenish - grey colors whereas Tephrite is available in black, brown, colourless, green, grey, white colors. The commercial uses of Pyrolite are creating artwork, gemstone, jewelry, source of chromite, platinum, nickel and garnet, source of diamonds and that of Tephrite are production of lime, soil conditioner.
