Formation
Claystone is generally quite soft, but can be hard and brittle. It forms due to weathering of mudstone.
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 Claystone and Granophyre
Here you can know more about Claystone and Granophyre. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Claystone and Granophyre consists of mineral content and compound content. The mineral content of Claystone includes Biotite, Chlorite, Feldspar, Micas, Muscovite or Illite, Plagioclase, Pyrite, Quartz and mineral content of Granophyre includes Hornblade, Orthoclase, Plagioclase, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Claystone vs Granophyre, the texture, color and appearance plays an important role in determining the type of rock. Claystone is available in black, blue, brown, green, grey, orange, red, white, yellow colors whereas, Granophyre is available in black, grey, orange, pink, white colors. Appearance of Claystone is Rough and Dull and that of Granophyre is Veined or Pebbled. Properties of rock is another aspect for Claystone vs Granophyre. The hardness of Claystone is 3.5-4 and that of Granophyre is 6-7. The types of Claystone are Claystone 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 Claystone and Granophyre is white. The specific heat capacity of Claystone 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.Claystone is heat resistant, impact resistant whereas Granophyre is heat resistant, wear resistant.
