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.
  
Gritstone is a type of sedimentary rock which was formed on the floors of wide river deltas where the grit deposits were laid down, with every tide or flood dumping another layer of sediment.

More about Granophyre and Gritstone
Here you can know more about Granophyre and Gritstone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Granophyre and Gritstone consists of mineral content and compound content. The mineral content of Granophyre includes Hornblade, Orthoclase, Plagioclase, Quartz and mineral content of Gritstone includes Calcite, Clay Minerals, Feldspar, Micas, Quartz. You can also check out the list of all . When we have to compare Granophyre vs Gritstone, 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, Gritstone is available in beige, black, brown, colourless, cream, dark brown, green, grey, light green, light to dark grey, pink, red, white, yellow colors. Appearance of Granophyre is Veined or Pebbled and that of Gritstone is Layered and Foliated. Properties of rock is another aspect for Granophyre vs Gritstone. Hardness of Granophyre and Gritstone is 6-7. The types of Granophyre are Not Available whereas types of Gritstone are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Granophyre and Gritstone is white. The specific heat capacity of Granophyre is 0.79 kJ/Kg K and that of Gritstone is 0.92 kJ/Kg K.
