5 Formation

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.

Pumice rock forms when the magma cools so quickly that atoms in the melt are not able to arrange themselves into a crystalline structure.

Granodiorite vs Pumice 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 Pumice Reserves. Granodiorite is a coarse-grained intrusive igneous rock containing quartz and plagioclase, and which has composition in between granite and diorite. Pumice is a volcanic rock that consists of highly vesicular rough textured volcanic glass, which may or may not contain crystals. 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 Pumice information and Granodiorite vs Pumice characteristics in the upcoming sections.

More about Granodiorite and Pumice

Here you can know more about Granodiorite and Pumice. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Granodiorite and Pumice 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 Pumice includes Aluminum Oxides, Calcite, Carbonate, Iron Oxides, Silica. You can also check out the list of all Igneous Rocks. When we have to compare Granodiorite vs Pumice, 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, Pumice is available in beige, colourless, grey, light green, light grey, pink, white, yellow- grey colors. Appearance of Granodiorite is Veined or Pebbled and that of Pumice is Vesicular. Properties of rock is another aspect for Granodiorite vs Pumice. Hardness of Granodiorite and Pumice is 6. The types of Granodiorite are Not Available whereas types of Pumice are Scoria. 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 Pumice is white, greenish white or grey. The specific heat capacity of Granodiorite is 0.79 kJ/Kg K and that of Pumice is 0.87 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 Pumice is impact resistant, pressure resistant.
