Granodiorite vs Adakite


Adakite vs Granodiorite


Definition

Definition
Granodiorite is a coarse-grained intrusive igneous rock containing quartz and plagioclase, and which has composition in between granite and diorite   
Adakite is an intermediate to felsic volcanic rock that has geochemical characteristics of magma which is said to be formed by partial melting of altered basalt that is subducted below volcanic arcs

Formation

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.   
Adakite rocks are formed when the hydrous fluids are released from minerals that break down in metamorphosed basalt, and rise into the mantle they initiate partial melting.

Granodiorite vs Adakite Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Granodiorite and Adakite Reserves. Granodiorite is a coarse-grained intrusive igneous rock containing quartz and plagioclase, and which has composition in between granite and diorite. Adakite is an intermediate to felsic volcanic rock that has geochemical characteristics of magma which is said to be formed by partial melting of altered basalt that is subducted below volcanic arcs. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Granodiorite vs Adakite information and Granodiorite vs Adakite characteristics in the upcoming sections.

Granodiorite vs Adakite 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 Adakite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Granodiorite and Properties of Adakite. Learn more about Granodiorite vs Adakite 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 Adakite include Decorative aggregates, Floor tiles, Homes, Hotels and Kitchens. Due to some exceptional properties of Granodiorite and Adakite, they have various applications in construction industry. The uses of Granodiorite in construction industry include As dimension stone and that of Adakite include As dimension stone, Cobblestones, Rail track ballast, Roadstone.

More about Granodiorite and Adakite

Here you can know more about Granodiorite and Adakite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Granodiorite and Adakite 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 Adakite includes Olivine, Plagioclase, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Granodiorite vs Adakite, 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, Adakite is available in black, brown, light to dark grey colors. Appearance of Granodiorite is Veined or Pebbled and that of Adakite is Dull and Soft. Properties of rock is another aspect for Granodiorite vs Adakite. The hardness of Granodiorite is 6 and that of Adakite is 3-4. The types of Granodiorite are Not Available whereas types of Adakite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Granodiorite is white while that of Adakite is bluish black. The specific heat capacity of Granodiorite is 0.79 kJ/Kg K and that of Adakite is Not Available. 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 Adakite is heat resistant, pressure resistant, wear resistant.
