Formation
Granophyre 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 Granophyre and Tephrite
Here you can know more about Granophyre and Tephrite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Granophyre and Tephrite consists of mineral content and compound content. The mineral content of Granophyre includes Hornblade, Orthoclase, Plagioclase, Quartz and mineral content of Tephrite includes Alkali feldspar, Nepheline, Plagioclase, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Granophyre vs Tephrite, the texture, color and appearance plays an important role in determining the type of rock. Granophyre is available in black, grey, orange, pink, white colors whereas, Tephrite is available in black, brown, colourless, green, grey, white colors. Appearance of Granophyre is Veined or Pebbled and that of Tephrite is Vesicular. Properties of rock is another aspect for Granophyre vs Tephrite. The hardness of Granophyre is 6-7 and that of Tephrite is 6.5. The types of Granophyre are Not Available whereas types of Tephrite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Granophyre is white while that of Tephrite is bluish black. The specific heat capacity of Granophyre is 0.79 kJ/Kg K and that of Tephrite 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.Granophyre is heat resistant, wear resistant whereas Tephrite is heat resistant, impact resistant.
