Archaeological Significance
Formation
Evaporite is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.
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 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. Evaporite vs Diorite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Evaporite and Properties of Diorite. Learn more about Evaporite vs Diorite in the next section. The interior uses of Evaporite include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration whereas the interior uses of Diorite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Evaporite and Diorite, they have various applications in construction industry. The uses of Evaporite in construction industry 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 and that of Diorite include As dimension stone, Cement manufacture, Cobblestones, Construction aggregate, For road aggregate.
More about Evaporite and Diorite
Here you can know more about Evaporite and Diorite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Evaporite and Diorite consists of mineral content and compound content. The mineral content of Evaporite includes Calcite, Cancrinite, Gypsum, Kyanite, Magnetite 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 Sedimentary Rocks. When we have to compare Evaporite vs Diorite, the texture, color and appearance plays an important role in determining the type of rock. Evaporite is available in green, grey, silver, white colors whereas, Diorite is available in black, brown, light to dark grey, white colors. Appearance of Evaporite is Glassy, Vesicular and Foilated and that of Diorite is Shiny. Properties of rock is another aspect for Evaporite vs Diorite. The hardness of Evaporite is 2-3 and that of Diorite is 6-7. The types of Evaporite are Sedimentary rock whereas types of Diorite are Plagioclase Diorite and Quartz Diorite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Evaporite is white while that of Diorite is bluish black. The specific heat capacity of Evaporite is 0.92 kJ/Kg K and that of Diorite 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.Evaporite is heat resistant, pressure resistant whereas Diorite is heat resistant, pressure resistant, wear resistant.
