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.
Mangerite 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.

More about Tephrite and Mangerite
Here you can know more about Tephrite and Mangerite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Tephrite and Mangerite consists of mineral content and compound content. The mineral content of Tephrite includes Alkali feldspar, Nepheline, Plagioclase, Pyroxene and mineral content of Mangerite includes Albite, Amphibole, Apatite, Biotite, Feldspar, Hornblade, Ilmenite, Magnetite, Muscovite or Illite, Olivine, Plagioclase, Pyroxene, Quartz, Sulfides, Titanite, Zircon. You can also check out the list of all Igneous Rocks. When we have to compare Tephrite vs Mangerite, 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, Mangerite is available in black, brown, light to dark grey, white colors. Appearance of Tephrite is Vesicular and that of Mangerite is Shiny. Properties of rock is another aspect for Tephrite vs Mangerite. The hardness of Tephrite is 6.5 and that of Mangerite is 6-7. The types of Tephrite are Igneous rock whereas types of Mangerite are Plutonic rock. 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 Mangerite is white. The specific heat capacity of Tephrite is 0.92 kJ/Kg K and that of Mangerite is 0.92 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 Mangerite is heat resistant, impact resistant, pressure resistant.
