Formation
Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.
Granodiorite is an intrusive igneous rock which is very hard, crystalline and is visibly homogeneous in texture and forms by melting of continental rocks.

Charnockite vs Granodiorite 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. Charnockite vs Granodiorite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Charnockite and Properties of Granodiorite. Learn more about Charnockite vs Granodiorite in the next section. The interior uses of Charnockite include Bathrooms, Countertops, Decorative aggregates, Entryways, Floor tiles, Homes, Hotels, Kitchens and Stair treads whereas the interior uses of Granodiorite include Bathrooms, Countertops, Decorative aggregates, Entryways, Floor tiles, Flooring, Homes, Hotels, Interior decoration and Stair treads. Due to some exceptional properties of Charnockite and Granodiorite, they have various applications in construction industry. The uses of Charnockite in construction industry include As dimension stone and that of Granodiorite include As dimension stone.
More about Charnockite and Granodiorite
Here you can know more about Charnockite and Granodiorite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Charnockite and Granodiorite consists of mineral content and compound content. The mineral content of Charnockite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Olivine, Plagioclase, Pyroxene, Quartz and mineral content of Granodiorite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Pyroxene, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Charnockite vs Granodiorite, the texture, color and appearance plays an important role in determining the type of rock. Charnockite is available in black, grey, orange, pink, white colors whereas, Granodiorite is available in black, grey, orange, pink, white colors. Appearance of Charnockite is Veined or Pebbled and that of Granodiorite is Veined or Pebbled. Properties of rock is another aspect for Charnockite vs Granodiorite. The hardness of Charnockite is 6-7 and that of Granodiorite is 6. The types of Charnockite are Enderbite whereas types of Granodiorite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Charnockite and Granodiorite is white. The specific heat capacity of Charnockite is Not Available and that of Granodiorite 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.Charnockite is heat resistant, wear resistant whereas Granodiorite is heat resistant, wear resistant.
