Formation
Granulite is a fine-grained granular metamorphic rock in which the main component minerals are feldspars and quartz and forms at high temperature and pressure conditions.
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 Granulite and Granophyre
Here you can know more about Granulite and Granophyre. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Granulite and Granophyre consists of mineral content and compound content. The mineral content of Granulite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Quartz and mineral content of Granophyre includes Hornblade, Orthoclase, Plagioclase, Quartz. You can also check out the list of all Metamorphic Rocks. When we have to compare Granulite vs Granophyre, the texture, color and appearance plays an important role in determining the type of rock. Granulite is available in black, brown colors whereas, Granophyre is available in black, grey, orange, pink, white colors. Appearance of Granulite is Veined or Pebbled and that of Granophyre is Veined or Pebbled. Properties of rock is another aspect for Granulite vs Granophyre. Hardness of Granulite and Granophyre is 6-7. The types of Granulite are Metamorphic rock whereas types of Granophyre are Intermediate intrusive rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Granulite and Granophyre is white. The specific heat capacity of Granulite is 0.14 kJ/Kg K and that of Granophyre 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.Granulite is heat resistant, wear resistant whereas Granophyre is heat resistant, wear resistant.
