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.

More about Tephrite and Marble
Here you can know more about Tephrite and Marble. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Tephrite and Marble consists of mineral content and compound content. The mineral content of Tephrite includes Alkali feldspar, Nepheline, Plagioclase, Pyroxene and mineral content of Marble includes Garnet, Graphite, Olivine, Pyrite, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Tephrite vs Marble, the texture, color and appearance plays an important role in determining the type of rock. Tephrite is available in black, brown, green, grey, white colors whereas, Marble is available in black, blue, brown, grey, pink, white colors. Appearance of Tephrite is Vesicular and that of Marble is Veined and Shiny. Properties of rock is another aspect for Tephrite vs Marble. The hardness of Tephrite is 6.5 and that of Marble is 3-4. The types of Tephrite are Igneous rock whereas types of Marble are Breccia Marble, Carrara Marble, Calacatta marble, Cultured Marble, Polished Marble, Honed Marble, Sand Marble. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Tephrite is bluish black while that of Marble is white. The specific heat capacity of Tephrite is 0.92 kJ/Kg K and that of Marble is 0.88 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Tephrite is heat resistant, impact resistant whereas Marble is heat resistant.
