1 Definition

1.1 Definition

Shale is a fine-grained sedimentary rock which is formed by the compaction of silt and clay-size mineral particles

Dolomite is a sedimentary rock containing more than 50 percent of the mineral dolomite by weight

5 Formation

5.1 Formation

Shale forms when very fine-grained clay particles are deposited in water which settle at the bottom of water bodies. They are later compacted hence forming shale.

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

Shale 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 Shale and Dolomite Reserves. Shale is a fine-grained sedimentary rock which is formed by the compaction of silt and clay-size mineral particles. 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 Shale vs Dolomite information and Shale vs Dolomite characteristics in the upcoming sections.

More about Shale and Dolomite

Here you can know more about Shale and Dolomite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Shale and Dolomite consists of mineral content and compound content. The mineral content of Shale includes Albite, Biotite, Calcite, Chert, Chlorite, Dolomite, Hematite, Micas, Muscovite or Illite, Pyrite, Quartz, Silica, Sulfides 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 Shale vs Dolomite, the texture, color and appearance plays an important role in determining the type of rock. Shale is available in black, brown, buff, green, grey, red, yellow colors whereas, Dolomite is available in black, brown, colourless, green, grey, pink, white colors. Appearance of Shale is Muddy and that of Dolomite is Glassy or Pearly. Properties of rock is another aspect for Shale vs Dolomite. The hardness of Shale is 3 and that of Dolomite is 3.5-4. The types of Shale are Red Shale, Black Shale, Green Shale, Grey Shale and Yellow Shale 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 Shale and Dolomite is white. The specific heat capacity of Shale 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.Shale is heat resistant, impact resistant whereas Dolomite is heat resistant, pressure resistant, wear resistant.
