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.

Limestone is a sedimentary rock which is mainly made up of calcium carbonate.

All about Tephrite and Limestone Properties

Know all about Tephrite and Limestone properties here. All properties of rocks are important as they define the type of rock and its application. Tephrite belongs to Igneous Rocks while Limestone belongs to Sedimentary Rocks.Texture of Tephrite is Aphanitic to Porphyritic whereas that of Limestone is Clastic or Non-Clastic. Tephrite appears Vesicular and Limestone appears Rough and Banded. The luster of Tephrite is subvitreous to dull while that of Limestone is dull to pearly. Tephrite is available in black, brown, colourless, green, grey, white colors whereas Limestone is available in beige, black, blue, brown, cream, gold, green, grey, light green, light grey, linen, pink, red, rust, silver, white, yellow colors. The commercial uses of Tephrite are production of lime, soil conditioner and that of Limestone are animal feed filler, as a feed additive for livestock, paper industry, raw material for manufacture of quicklime, slaked lime, soil conditioner, used in aquariums, whiting material in toothpaste, paint and paper.
