Formation
When alkali feldspar is extracted from granite, it changes to granitoid and later, it becomes tonalite with quartz as major mineral.
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 Tonalite and Granophyre
Here you can know more about Tonalite and Granophyre. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Tonalite and Granophyre consists of mineral content and compound content. The mineral content of Tonalite includes Albite, Amphibole, Apatite, Biotite, Feldspar, Hornblade, Ilmenite, Magnetite, Manganese Oxides, Olivine, Plagioclase, Pyroxene, Quartz, Sulfides, Titanite, Zircon and mineral content of Granophyre includes Hornblade, Orthoclase, Plagioclase, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Tonalite vs Granophyre, the texture, color and appearance plays an important role in determining the type of rock. Tonalite is available in black, brown, light to dark grey, white colors whereas, Granophyre is available in black, grey, orange, pink, white colors. Appearance of Tonalite is Banded and Foilated and that of Granophyre is Veined or Pebbled. Properties of rock is another aspect for Tonalite vs Granophyre. Hardness of Tonalite and Granophyre is 6-7. The types of Tonalite are Dacite whereas types of Granophyre are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Tonalite is bluish black while that of Granophyre is white. The specific heat capacity of Tonalite is 0.92 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.Tonalite is heat resistant, pressure resistant, water resistant whereas Granophyre is heat resistant, wear resistant.
