5 Formation

5.1 Formation

Epidosite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

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

Epidosite 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 Epidosite and Dolomite Reserves. Epidosite is a highly altered epidote and quartz bearing rock which is a type of metasomatite, essentially altered basalt. 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 Epidosite vs Dolomite information and Epidosite vs Dolomite characteristics in the upcoming sections.
