Formation
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.
  
Evaporite is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.

Diorite vs Evaporite 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. Diorite vs Evaporite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Diorite and Properties of Evaporite. Learn more about Diorite vs Evaporite in the next section. The interior uses of Diorite include Decorative aggregates and Interior decoration whereas the interior uses of Evaporite include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration. Due to some exceptional properties of Diorite and Evaporite, they have various applications in construction industry. The uses of Diorite in construction industry include As dimension stone, Cement manufacture, Cobblestones, Construction aggregate, For road aggregate and that of Evaporite include As a flux in the production of steel and pig iron, As a sintering agent in steel industry to process iron ore, As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories.
More about Diorite and Evaporite
Here you can know more about Diorite and Evaporite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Diorite and Evaporite consists of mineral content and compound content. The mineral content of Diorite includes Albite, Amphibole, Apatite, Biotite, Feldspar, Hornblade, Ilmenite, Magnetite, Muscovite or Illite, Olivine, Plagioclase, Pyroxene, Quartz, Sulfides, Titanite, Zircon and mineral content of Evaporite includes Calcite, Cancrinite, Gypsum, Kyanite, Magnetite. You can also check out the list of all Igneous Rocks. When we have to compare Diorite vs Evaporite, the texture, color and appearance plays an important role in determining the type of rock. Diorite is available in black, brown, light to dark grey, white colors whereas, Evaporite is available in colourless, green, grey, silver, white colors. Appearance of Diorite is Shiny and that of Evaporite is Glassy, Vesicular and Foilated. Properties of rock is another aspect for Diorite vs Evaporite. The hardness of Diorite is 6-7 and that of Evaporite is 2-3. The types of Diorite are Not Available whereas types of Evaporite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Diorite is bluish black while that of Evaporite is white. The specific heat capacity of Diorite is Not Available and that of Evaporite is 0.92 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Diorite is heat resistant, pressure resistant, wear resistant whereas Evaporite is heat resistant, pressure resistant.
