Granodiorite vs Hornfels

Definition

Definition

Granodiorite is a coarse-grained intrusive igneous rock containing quartz and plagioclase, and which has composition in between granite and diorite
Hornfels is a metamorphic rock formed by the contact between mudstone or other clay rich rock, and a hot igneous body, and represents a heat altered equivalent of the original rock

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.
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Hornfels is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

Granodiorite vs Hornfels 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 Hornfels Reserves. Granodiorite is a coarse-grained intrusive igneous rock containing quartz and plagioclase, and which has composition in between granite and diorite. Hornfels is a metamorphic rock formed by the contact between mudstone or other clay rich rock, and a hot igneous body, and represents a heat altered equivalent of the original rock. 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 Hornfels information and Granodiorite vs Hornfels characteristics in the upcoming sections.

Granodiorite vs Hornfels 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 Hornfels characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Granodiorite and Properties of Hornfels. Learn more about Granodiorite vs Hornfels 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 Hornfels include Decorative aggregates, Flooring, Homes and Interior decoration. Due to some exceptional properties of Granodiorite and Hornfels, they have various applications in construction industry. The uses of Granodiorite in construction industry include As dimension stone and that of Hornfels include For road aggregate, Roadstone.

More about Granodiorite and Hornfels

Here you can know more about Granodiorite and Hornfels. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Granodiorite and Hornfels 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 Hornfels includes Andalusite. You can also check out the list of all Igneous Rocks. When we have to compare Granodiorite vs Hornfels, 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, Hornfels is available in brown, dark greenish - grey, green, reddish brown colors. Appearance of Granodiorite is Veined or Pebbled and that of Hornfels is Dull. Properties of rock is another aspect for Granodiorite vs Hornfels. The hardness of Granodiorite is 6 and that of Hornfels is 2-3. The types of Granodiorite are Granodiorite whereas types of Hornfels are Biotite hornfels. 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 Hornfels is . The specific heat capacity of Granodiorite is 0.79 kJ/Kg K and that of Hornfels is 0.84 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 Hornfels is heat resistant, impact resistant, pressure resistant.
