Formation
Granodiorite is an intrusive igneous rock which is very hard, crystalline and is visibly homogeneous in texture and forms by melting of continental rocks.
Flint is formed by the decomposition and compaction of various organisms such as sponges and diatoms under the water.

More about Granodiorite and Flint
Here you can know more about Granodiorite and Flint. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Granodiorite and Flint consists of mineral content and compound content. The mineral content of Granodiorite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Pyroxene, Quartz and mineral content of Flint includes Silicon. You can also check out the list of all Igneous Rocks. When we have to compare Granodiorite vs Flint, the texture, color and appearance plays an important role in determining the type of rock. Granodiorite is available in black, grey, orange, pink, white colors whereas, Flint is available in black, brown, green, grey, red, white colors. Appearance of Granodiorite is Veined or Pebbled and that of Flint is Glassy or Pearly. Properties of rock is another aspect for Granodiorite vs Flint. The hardness of Granodiorite is 6 and that of Flint is 7. The types of Granodiorite are Not Available whereas types of Flint are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Granodiorite and Flint is white. The specific heat capacity of Granodiorite is 0.79 kJ/Kg K and that of Flint is 0.74 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Granodiorite is heat resistant, wear resistant whereas Flint is heat resistant, impact resistant, pressure resistant, wear resistant.
