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.   
Granite is an igneous rock which is very hard, crystalline and is visibly homogeneous in texture and forms by melting of continental rocks

Dolomite vs Rapakivi Granite 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 Rapakivi Granite Reserves. Dolomite is a sedimentary rock containing more than 50 percent of the mineral dolomite by weight. Rapakivi Granite is a hornblende-biotite Granite containing large rounded crystals of orthoclase which are mantled with oligoclase. 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 Rapakivi Granite information and Dolomite vs Rapakivi Granite characteristics in the upcoming sections.
