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.
Theralite 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 Theralite
Here you can know more about Granophyre and Theralite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Granophyre and Theralite consists of mineral content and compound content. The mineral content of Granophyre includes Hornblade, Orthoclase, Plagioclase, Quartz and mineral content of Theralite includes Augite, Olivine, Plagioclase, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Granophyre vs Theralite, 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, Theralite is available in dark grey to black colors. Appearance of Granophyre is Veined or Pebbled and that of Theralite is Veined and Shiny. Properties of rock is another aspect for Granophyre vs Theralite. The hardness of Granophyre is 6-7 and that of Theralite is 7. The types of Granophyre are Intermediate intrusive rock whereas types of Theralite are Teschenite and Essexite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Granophyre and Theralite is white. The specific heat capacity of Granophyre is 0.79 kJ/Kg K and that of Theralite is 0.74 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 Theralite is impact resistant, pressure resistant, wear resistant.
