5 Formation
5.1 Formation
Dolomite rocks are originally deposited as calcite or aragonite rich limestone, but during diagenesis process, the calcite or aragonite is transformed into dolomite.
Blueschist forms due to the metamorphism of basalt and other rocks with similar composition at high pressures and low temperatures and approximately corresponding to a depth of 15 to 30 kilometers and 200 to 500 °C.

Dolomite vs Blueschist 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 Blueschist Reserves. Dolomite is a sedimentary rock containing more than 50 percent of the mineral dolomite by weight. Blueschist is a metamorphic rock which is generally blue in color and is formed under conditions of high pressure and low temperature. 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 Blueschist information and Dolomite vs Blueschist characteristics in the upcoming sections.

Dolomite vs Blueschist 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 Blueschist characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Dolomite and Properties of Blueschist. Learn more about Dolomite vs Blueschist in the next section. The interior uses of Dolomite include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Blueschist include Floor tiles, Flooring, Homes, Hotels and Kitchens.
