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.
Foidolites 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.

Granodiorite vs Foidolite Characteristics
Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Granodiorite vs Foidolite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Granodiorite and Properties of Foidolite. Learn more about Granodiorite vs Foidolite in the next section. The interior uses of Granodiorite include Bathrooms, Countertops, Decorative aggregates, Entryways, Floor tiles, Flooring, Homes, Hotels, Interior decoration and Stair treads whereas the interior uses of Foidolite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Granodiorite and Foidolite, they have various applications in construction industry.

More about Granodiorite and Foidolite
Here you can know more about Granodiorite and Foidolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Granodiorite and Foidolite 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 Foidolite includes Amphibole, Biotite, Feldspar, Olivine, Plagioclase, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Granodiorite vs Foidolite, 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, Foidolite is available in black, brown, green, grey, pink, white colors. Appearance of Granodiorite is Veined or Pebbled and that of Foidolite is Dull. Properties of rock is another aspect for Granodiorite vs Foidolite. The hardness of Granodiorite is 6 and that of Foidolite is 1.5. The types of Granodiorite are Granodiorite whereas types of Foidolite are Igneous rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Granodiorite and Foidolite is white. The specific heat capacity of Granodiorite is 0.79 kJ/Kg K and that of Foidolite 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.Granodiorite is heat resistant, wear resistant whereas Foidolite is heat resistant, wear resistant.
