Formation

Formation

Siltstone is a type of sedimentary rock which is formed from fine rock particles. As the particles of eroded rock travel along with water, the edges of the rock are worn-out by water into a rounded shape.
Dolomite rocks are originally deposited as calcite or aragonite rich limestone, but during diagenesis process, the calcite or aragonite is transformed into dolomite.

Siltstone 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 Siltstone and Dolomite Reserves. Siltstone can be defined as a fine-grained sedimentary rock which mainly consists of consolidated silt. 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 Siltstone vs Dolomite information and Siltstone vs Dolomite characteristics in the upcoming sections.

Siltstone vs Dolomite 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. Siltstone vs Dolomite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Siltstone and Properties of Dolomite. Learn more about Siltstone vs Dolomite in the next section. The interior uses of Siltstone include Decorative aggregates and Interior decoration whereas the interior uses of Dolomite include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Siltstone and Dolomite, they have various applications in construction industry. The uses of Siltstone in construction industry include Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for the manufacture of mortar and that of Dolomite include As a flux in the production of steel and pig iron, As a sintering agent in steel industry to process iron ore, As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories, Production of glass and ceramics, Serves as an oil and gas reservoir rock.

More about Siltstone and Dolomite

Here you can know more about Siltstone and Dolomite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Siltstone and Dolomite consists of mineral content and compound content. The mineral content of Siltstone includes Calcite, Clay, Clay Minerals, Feldspar, Micas, Quartz, Sand, Silica, Silt 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 Siltstone vs Dolomite, the texture, color and appearance plays an important role in determining the type of rock. Siltstone is available in brown, red, reddish brown colors whereas, Dolomite is available in black, brown, green, grey, pink, white colors. Appearance of Siltstone is Rough and that of Dolomite is Glassy or Pearly. Properties of rock is another aspect for Siltstone vs Dolomite. The hardness of Siltstone is 6-7 and that of Dolomite is 3.5-4. The types of Siltstone are Siltstone 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 Siltstone and Dolomite is white. The specific heat capacity of Siltstone is 0.84 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.Siltstone is heat resistant, impact resistant, pressure resistant, water resistant whereas Dolomite is heat resistant, pressure resistant, wear resistant.
