Definition
Granophyre is a type of granitic rock which consists of intergrown feldspar and quartz crystals in a medium to fine grained groundmass
Claystone is a fine-grained, dark gray to pink sedimentary rock which mainly consists of compacted and hardened clay

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.
Claystone is generally quite soft, but can be hard and brittle. It forms due to weathering of mudstone.

More about Granophyre and Claystone
Here you can know more about Granophyre and Claystone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Granophyre and Claystone consists of mineral content and compound content. The mineral content of Granophyre includes Hornblade, Orthoclase, Plagioclase, Quartz and mineral content of Claystone includes Biotite, Chlorite, Feldspar, Micas, Muscovite or Illite, Plagioclase, Pyrite, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Granophyre vs Claystone, 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, Claystone is available in black, blue, brown, green, grey, orange, red, white, yellow colors. Appearance of Granophyre is Veined or Pebbled and that of Claystone is Rough and Dull. Properties of rock is another aspect for Granophyre vs Claystone. The hardness of Granophyre is 6-7 and that of Claystone is 3.5-4. The types of Granophyre are Intermediate intrusive rock whereas types of Claystone are Claystone. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Granophyre and Claystone is white. The specific heat capacity of Granophyre is 0.79 kJ/Kg K and that of Claystone 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 Claystone is heat resistant, impact resistant.
