Formation
Evaporite is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.
When alkali feldspar is extracted from granite, it changes to granitoid and later, it becomes tonalite with quartz as major mineral.

Evaporite vs Tonalite 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 Tonalite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Evaporite and Properties of Tonalite. Learn more about Evaporite vs Tonalite in the next section. The interior uses of Evaporite include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration whereas the interior uses of Tonalite include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration. Due to some exceptional properties of Evaporite and Tonalite, 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 Tonalite include As dimension stone, Cement manufacture, Cobblestones, Construction aggregate, For road aggregate.
More about Evaporite and Tonalite
Here you can know more about Evaporite and Tonalite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Evaporite and Tonalite consists of mineral content and compound content. The mineral content of Evaporite includes Calcite, Cancrinite, Gypsum, Kyanite, Magnetite and mineral content of Tonalite includes Albite, Amphibole, Apatite, Biotite, Feldspar, Hornblade, Ilmenite, Magnetite, Manganese Oxides, 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 Tonalite, the texture, color and appearance plays an important role in determining the type of rock. Evaporite is available in colourless, green, grey, silver, white colors whereas, Tonalite is available in black, brown, light to dark grey, white colors. Appearance of Evaporite is Glassy, Vesicular and Foilated and that of Tonalite is Banded and Foilated. Properties of rock is another aspect for Evaporite vs Tonalite. The hardness of Evaporite is 2-3 and that of Tonalite is 6-7. The types of Evaporite are Not Available whereas types of Tonalite are Dacite. 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 Tonalite is bluish black. The specific heat capacity of Evaporite is 0.92 kJ/Kg K and that of Tonalite 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.Evaporite is heat resistant, pressure resistant whereas Tonalite is heat resistant, pressure resistant, water resistant.
