1.1 Definition

Chalk is a soft, white, powdery limestone consisting mainly of fossil shells of foraminifers

A hydration and metamorphic transformation of ultramafic rock from the Earth's mantle is called as serpentinization, a group of minerals is formed by serpentinization compose rock 'serpentinite'.

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.

Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Serpentinite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

Chalk vs Serpentinite 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 Serpentinite Reserves. Chalk is a soft, white, powdery limestone consisting mainly of fossil shells of foraminifers. A hydration and metamorphic transformation of ultramafic rock from the Earth's mantle is called as serpentinization, a group of minerals is formed by serpentinization compose rock 'serpentinite'.. 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 Serpentinite information and Chalk vs Serpentinite characteristics in the upcoming sections.

Chalk vs Serpentinite 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 Serpentinite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Chalk and Properties of Serpentinite. Learn more about Chalk vs Serpentinite in the next section. The interior uses of Chalk include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Serpentinite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Chalk and Serpentinite, 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 Serpentinite include As dimension stone, Cement manufacture, For road aggregate, Making natural cement.

More about Chalk and Serpentinite

Here you can know more about Chalk and Serpentinite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Chalk and Serpentinite consists of mineral content and compound content. The mineral content of Chalk includes Calcite, Clay, Clay Minerals, Quartz, Sand and mineral content of Serpentinite includes Carbonate, Magnetite, Pyrrhotite, Serpentine, Sulfides. You can also check out the list of all Sedimentary Rocks. When we have to compare Chalk vs Serpentinite, the texture, color and appearance plays an important role in determining the type of rock. Chalk is available in grey, white, yellow colors whereas, Serpentinite is available in black, brown, colourless, green, grey, white colors. Appearance of Chalk is Soft and that of Serpentinite is Rough and Dull. Properties of rock is another aspect for Chalk vs Serpentinite. The hardness of Chalk is 1 and that of Serpentinite is 3-5. The types of Chalk are Not Available whereas types of Serpentinite are Jadeitite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Chalk is white while that of Serpentinite is white, greenish white or grey. The specific heat capacity of Chalk is 0.90 kJ/Kg K and that of Serpentinite is 0.95 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 Serpentinite is heat resistant.
