Formation

Formation
Dolomite rocks are originally deposited as calcite or aragonite rich limestone, but during diagenesis process, the calcite or aragonite is transformed into dolomite.   
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.

Dolomite 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 Dolomite and Tuff Reserves. Dolomite is a sedimentary rock containing more than 50 percent of the mineral dolomite by weight. 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 Dolomite vs Tuff information and Dolomite vs Tuff characteristics in the upcoming sections.

Dolomite 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. Dolomite vs Tuff characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Dolomite and Properties of Tuff. Learn more about Dolomite vs Tuff in the next section. The interior uses of Dolomite include Decorative aggregates, 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 Dolomite and Tuff, they have various applications in construction industry. The uses of Dolomite 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, Production of glass and ceramics, Serves as an oil and gas reservoir rock and that of Tuff include Building houses or walls, Construction aggregate.

More about Dolomite and Tuff

Here you can know more about Dolomite and Tuff. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Dolomite and Tuff consists of mineral content and compound content. The mineral content of Dolomite includes Clay Minerals, Pyrite, Quartz, Sulfides and mineral content of Tuff includes Calcite, Chlorite. You can also check out the list of all Sedimentary Rocks. When we have to compare Dolomite vs Tuff, the texture, color and appearance plays an important role in determining the type of rock. Dolomite is available in black, brown, colourless, green, grey, pink, white colors whereas, Tuff is available in brown, grey, yellow colors. Appearance of Dolomite is Glassy or Pearly and that of Tuff is Dull, Vesicular and Foilated. Properties of rock is another aspect for Dolomite vs Tuff. The hardness of Dolomite is 3.5-4 and that of Tuff is 4-6. The types of Dolomite are Boninite and Jasperoid 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 Dolomite and Tuff is white. The specific heat capacity of Dolomite 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.Dolomite is heat resistant, pressure resistant, wear resistant whereas Tuff is heat resistant, impact resistant, pressure resistant, wear resistant.
