5.1 Formation

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

Tuff is formed when large masses of ash and sand which are mixed with hot gases are ejected by a volcano and avalanche rapidly down its slopes.

Evaporite vs Tuff 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 Evaporite and Tuff Reserves. A water-soluble mineral sediment resulting from concentration and crystallization by evaporation from an aqueous solution. Tuff is a type of rock made of volcanic ash ejected from a vent during a volcanic eruption. 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 Evaporite vs Tuff information and Evaporite vs Tuff characteristics in the upcoming sections.

Evaporite vs Tuff 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 Tuff characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Evaporite and Properties of Tuff. Learn more about Evaporite vs Tuff in the next section. The interior uses of Evaporite include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration whereas the interior uses of Tuff include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration. Due to some exceptional properties of Evaporite and Tuff, 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 Tuff include Building houses or walls, Construction aggregate.

More about Evaporite and Tuff

Here you can know more about Evaporite and Tuff. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Evaporite and Tuff consists of mineral content and compound content. The mineral content of Evaporite includes Calcite, Cancrinite, Gypsum, Kyanite, Magnetite and mineral content of Tuff includes Calcite, Chlorite. You can also check out the list of all Sedimentary Rocks. When we have to compare Evaporite vs Tuff, 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, Tuff is available in brown, grey, yellow colors. Appearance of Evaporite is Glassy, Vesicular and Foilated and that of Tuff is Dull, Vesicular and Foilated. Properties of rock is another aspect for Evaporite vs Tuff. The hardness of Evaporite is 2-3 and that of Tuff is 4-6. The types of Evaporite are Not Available whereas types of Tuff are Welded tuff, Rhyolitic tuff, Basaltic tuff, Trachyte tuff, Andesitic tuff and Ignimbrite.. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Evaporite and Tuff is white. The specific heat capacity of Evaporite is 0.92 kJ/Kg K and that of Tuff is 0.20 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 Tuff is heat resistant, impact resistant, pressure resistant, wear resistant.
