1 Definition
1.1 Definition
Chalk is a soft, white, powdery limestone consisting mainly of fossil shells of foraminifers
Dolomite is a sedimentary rock containing more than 50 percent of the mineral dolomite by weight
1.2 History
1.2.1 Origin
Unknown
Southern Alps, France
1.2.2 Discoverer

Dolomieu
1.3 Etymology
From old English cealc chalk, lime, plaster; pebble, from Greek khalix small pebble, in English transferred to the opaque, white, soft limestone
From French, from the name of Dolomieu (1750–1801), the French geologist who discovered the rock

5 Formation
5.1 Formation
Chalk is formed from lime mud, which accumulates on the sea floor which is then transformed into rock by geological processes.
Dolomite rocks are originally deposited as calcite or aragonite rich limestone, but during diagenesis process, the calcite or aragonite is transformed into dolomite.

Chalk 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 Chalk and Dolomite Reserves. Chalk is a soft, white, powdery limestone consisting mainly of fossil shells of foraminifers. 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 Chalk vs Dolomite information and Chalk vs Dolomite characteristics in the upcoming sections.

Chalk 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. Chalk vs Dolomite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Chalk and Properties of Dolomite. Learn more about Chalk vs Dolomite in the next section. The interior uses of Chalk include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Dolomite include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Chalk and Dolomite, they have various applications in construction industry. The uses of Chalk in construction industry include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for manufacture of quicklime and slaked lime, Source of calcium 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 Chalk and Dolomite

Here you can know more about Chalk and Dolomite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Chalk and Dolomite consists of mineral content and compound content. The mineral content of Chalk includes Calcite, Clay, Clay Minerals, Quartz, Sand 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 Chalk vs Dolomite, the texture, color and appearance plays an important role in determining the type of rock. Chalk is available in grey, white, yellow colors whereas, Dolomite is available in black, brown, colourless, green, grey, pink, white colors. Appearance of Chalk is Soft and that of Dolomite is Glassy or Pearly. Properties of rock is another aspect for Chalk vs Dolomite. The hardness of Chalk is 1 and that of Dolomite is 3.5-4. The types of Chalk are Not Available 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 Chalk and Dolomite is white. The specific heat capacity of Chalk is 0.90 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.Chalk is heat resistant whereas Dolomite is heat resistant, pressure resistant, wear resistant.
