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.
Essexite is a type of igneous rock, which is usually dark grey to black plutonic rock. For the formation of essexite, suitable magma with exact composition of K, Ba, Rb, Cs, Sr should be produced.

Dolomite vs Essexite  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 Essexite  Reserves. Dolomite is a sedimentary rock containing more than 50 percent of the mineral dolomite by weight. Essexite which is also known as nepheline monzogabbro, is a dark gray or black holocrystalline plutonic Iigneous Rock. 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 Essexite  information and Dolomite vs Essexite  characteristics in the upcoming sections.

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