5.1 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.

Chert forms when microcrystals of silicon dioxide grow within soft sediments that become limestone or chalk. The chert formation can be either of chemical or biological origin.

Granodiorite vs Chert 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 Chert Reserves. Granodiorite is a coarse-grained intrusive igneous rock containing quartz and plagioclase, and which has composition in between granite and diorite. Chert is a hard, dark, opaque sedimentary rock which is composed of silica with an amorphous fine-grained texture. 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 Chert information and Granodiorite vs Chert characteristics in the upcoming sections.

More about Granodiorite and Chert

Here you can know more about Granodiorite and Chert. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Granodiorite and Chert 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 Chert includes Quartz, Silicon. You can also check out the list of all Igneous Rocks. When we have to compare Granodiorite vs Chert, 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, Chert is available in black, brown, green, grey, red, white colors. Appearance of Granodiorite is Veined or Pebbled and that of Chert is Glassy or Pearly. Properties of rock is another aspect for Granodiorite vs Chert. The hardness of Granodiorite is 6 and that of Chert is 6.5-7. The types of Granodiorite are Not Available whereas types of Chert are Flint, Jasper, Radiolarite, Common Chert, Chalcedony, Agate, Onyx, Opal, Magadi-type Chert, Porcelanite, Siliceous Sinter. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Granodiorite and Chert is white. The specific heat capacity of Granodiorite is 0.79 kJ/Kg K and that of Chert 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 Chert is heat resistant, impact resistant, pressure resistant, wear resistant.
