5 Formation

5.1 Formation

Mudstone forms when very fine-grained clay particles are deposited in water which settle at the bottom of water bodies. They are buried and compacted by overlying sediment hence forming mudstone.

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

Mudstone 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 Mudstone and Dolomite Reserves. Mudstone is a fine-grained, dark gray sedimentary rock, which is formed from silt and clay and is similar to shale but has less laminations. 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 Mudstone vs Dolomite information and Mudstone vs Dolomite characteristics in the upcoming sections.

More about Mudstone and Dolomite

Here you can know more about Mudstone and Dolomite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Mudstone and Dolomite consists of mineral content and compound content. The mineral content of Mudstone includes Biotite, Chlorite, Feldspar, Micas, Muscovite or Illite, Plagioclase, Pyrite, Quartz and mineral content of Dolomite includes Clay Minerals, Pyrite, Quartz, Sulfides. You can also check out the list of all Sedimentary Rocks. When we have to compare Mudstone vs Dolomite, the texture, color and appearance plays an important role in determining the type of rock. Mudstone is available in black, blue, brown, green, grey, orange, red, white, yellow colors whereas, Dolomite is available in black, brown, colourless, green, grey, pink, white colors. Appearance of Mudstone is Rough and Dull and that of Dolomite is Glassy or Pearly. Properties of rock is another aspect for Mudstone vs Dolomite. The hardness of Mudstone is 2-3 and that of Dolomite is 3.5-4. The types of Mudstone are Marl, Shale and Argillite 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 Mudstone and Dolomite is white. The specific heat capacity of Mudstone is 0.39 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.Mudstone is heat resistant, impact resistant whereas Dolomite is heat resistant, pressure resistant, wear resistant.
