Formation

Formation
Scoria forms when magma containing huge amount of dissolved gas flows from a volcano during an eruption.   
Diorite is a coarse-grained intrusive igneous rock which contains large interlocking and randomly oriented crystals and forms when molten lava does not reach the Earth’s surface and cools down in the Earth’s crust.

Scoria vs Diorite 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 Scoria and Diorite Reserves. Scoria is a dark-colored extrusive igneous rock with abundant round bubble-like cavities. Diorite is a grey to dark-grey intermediate intrusive igneous rock composed principally of plagioclase feldspar,biotite, hornblende, and pyroxene. 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 Scoria vs Diorite information and Scoria vs Diorite characteristics in the upcoming sections.

Scoria vs Diorite 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. Scoria vs Diorite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Scoria and Properties of Diorite. Learn more about Scoria vs Diorite in the next section. The interior uses of Scoria include Decorative aggregates and Interior decoration whereas the interior uses of Diorite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Scoria and Diorite, they have various applications in construction industry. The uses of Scoria in construction industry include Cement manufacture, Construction aggregate, For road aggregate, In landscaping and drainage works and that of Diorite include As dimension stone, Cement manufacture, Cobblestones, Construction aggregate, For road aggregate.

More about Scoria and Diorite

Here you can know more about Scoria and Diorite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Scoria and Diorite consists of mineral content and compound content. The mineral content of Scoria includes Apatite, Biotite, Calcite, Feldspar, Hematite, Hornblade, Ilmenite, Magnetite, Olivine, Pyroxene, Quartz, Silica and mineral content of Diorite includes Albite, Amphibole, Apatite, Biotite, Feldspar, Hornblade, Ilmenite, Magnetite, Muscovite or Illite, Olivine, Plagioclase, Pyroxene, Quartz, Sulfides, Titanite, Zircon. You can also check out the list of all Igneous Rocks. When we have to compare Scoria vs Diorite, the texture, color and appearance plays an important role in determining the type of rock. Scoria is available in black, brown, dark grey to black, red colors whereas, Diorite is available in black, brown, light to dark grey, white colors. Appearance of Scoria is Glassy and Vesicular and that of Diorite is Shiny. Properties of rock is another aspect for Scoria vs Diorite. The hardness of Scoria is 5-6 and that of Diorite is 6-7. The types of Scoria are Not Available whereas types of Diorite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Scoria is white while that of Diorite is bluish black. The specific heat capacity of Scoria is Not Available and that of Diorite is Not Available. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Scoria is heat resistant, impact resistant, pressure resistant, wear resistant whereas Diorite is heat resistant, pressure resistant, wear resistant.
