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.

More about Tephrite and Monzogranite
Here you can know more about Tephrite and Monzogranite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Tephrite and Monzogranite consists of mineral content and compound content. The mineral content of Tephrite includes Alkali feldspar, Nepheline, Plagioclase, Pyroxene and mineral content of Monzogranite includes Apatite, Biotite, Hornblende, Microcline, Perthite, Plagioclase, Quartz, Titanite, Zircon. You can also check out the list of all Igneous Rocks. When we have to compare Tephrite vs Monzogranite, the texture, color and appearance plays an important role in determining the type of rock. Tephrite is available in black, brown, colourless, green, grey, white colors whereas, Monzogranite is available in black, grey, orange, pink, white colors. Appearance of Tephrite is Vesicular and that of Monzogranite is Veined or Pebbled. Properties of rock is another aspect for Tephrite vs Monzogranite. The hardness of Tephrite is 6.5 and that of Monzogranite is 6-7. The types of Tephrite are Not Available whereas types of Monzogranite are Muscovite-Biotite-Metagranite, Muscovite-Metagranite, Schollen-Metagranite and Biotite-Metagranite. 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 Monzogranite is white. The specific heat capacity of Tephrite is 0.92 kJ/Kg K and that of Monzogranite is 0.79 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 Monzogranite is heat resistant, wear resistant.
