Dolomite vs Dacite


Definition

Definition
Dacite is a volcanic igneous rock which is rintermediate in composition between andesite and rhyolite   
Dolomite is a sedimentary rock containing more than 50 percent of the mineral dolomite by weight

Formation

Formation
Dacitic magma is formed by the subduction of young oceanic crust under a thick felsic continental plate. Further, the Oceanic crust is hydrothermally altered as quartz and sodium are added.   
Dolomite rocks are originally deposited as calcite or aragonite rich limestone, but during diagenesis process, the calcite or aragonite is transformed into dolomite.

Dacite vs Dolomite 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 Dacite and Dolomite Reserves. Dacite is a volcanic igneous rock which is rintermediate in composition between andesite and rhyolite. Dolomite is a sedimentary rock containing more than 50 percent of the mineral dolomite by weight. 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 Dacite vs Dolomite information and Dacite vs Dolomite characteristics in the upcoming sections.

Dacite vs Dolomite 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. Dacite vs Dolomite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Dacite and Properties of Dolomite. Learn more about Dacite vs Dolomite in the next section. The interior uses of Dacite include Decorative aggregates, Entryways and Interior decoration whereas the interior uses of Dolomite include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Dacite and Dolomite, they have various applications in construction industry. The uses of Dacite in construction industry include As dimension stone, Construction aggregate, For road aggregate, Landscaping and that of Dolomite 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.

More about Dacite and Dolomite

Here you can know more about Dacite and Dolomite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Dacite and Dolomite consists of mineral content and compound content. The mineral content of Dacite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Magnetite, Plagioclase, Pyroxene, Quartz, Zircon and mineral content of Dolomite includes Clay Minerals, Pyrite, Quartz, Sulfides. You can also check out the list of all Igneous Rocks. When we have to compare Dacite vs Dolomite, the texture, color and appearance plays an important role in determining the type of rock. Dacite is available in bluish - grey, brown, grey, light to dark grey colors whereas, Dolomite is available in black, brown, colourless, green, grey, pink, white colors. Appearance of Dacite is Vesicular and that of Dolomite is Glassy or Pearly. Properties of rock is another aspect for Dacite vs Dolomite. The hardness of Dacite is 2-2.25 and that of Dolomite is 3.5-4. The types of Dacite are Footwall Dacite, Hanging wall Dacite, Tuff and Biotite Dacite whereas types of Dolomite are Boninite and Jasperoid. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Dacite and Dolomite is white. The specific heat capacity of Dacite is 0.92 kJ/Kg K and that of Dolomite 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.Dacite is heat resistant, impact resistant, pressure resistant, wear resistant whereas Dolomite is heat resistant, pressure resistant, wear resistant.
