Definition
Tephrite is an aphanitic to porphyritic textured, volcanic igneous rock
Marble is a non-foliated metamorphic rock which is composed of recrystallized carbonate which is formed when limestone is exposed to high temperatures and pressures over a long time

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.
Marble is a metamorphic rock produced from limestone in the earth crust. It is formed by the metamorphism of limestone.

All about Tephrite and Marble Properties
Know all about Tephrite and Marble properties here. All properties of rocks are important as they define the type of rock and its application. Tephrite belongs to Igneous Rocks while Marble belongs to Metamorphic Rocks.Texture of Tephrite is Aphanitic to Porphyritic whereas that of Marble is Granular. Tephrite appears Vesicular and Marble appears Veined and Shiny. The luster of Tephrite is subvitreous to dull while that of Marble is dull to pearly to subvitreous. Tephrite is available in black, brown, green, grey, white colors whereas Marble is available in black, blue, brown, grey, pink, white colors. The commercial uses of Tephrite are production of lime, soil conditioner and that of Marble are cemetery markers, commemorative tablets, creating artwork, curling, laboratory bench tops, paper industry, tombstones, used in aquariums, whiting material in toothpaste, paint and paper.
