1 Definition
1.1 Definition
Chert is a hard, dark, opaque sedimentary rock which is composed of silica with an amorphous fine-grained texture
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
Chert forms when microcrystals of silicon dioxide grow within soft sediments that become limestone or chalk. The chert formation can be either of chemical or biological origin.
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.

Chert 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 Chert and Serpentinite Reserves. Chert is a hard, dark, opaque sedimentary rock which is composed of silica with an amorphous fine-grained texture. 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 Chert vs Serpentinite information and Chert vs Serpentinite characteristics in the upcoming sections.

Chert 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. Chert vs Serpentinite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Chert and Properties of Serpentinite. Learn more about Chert vs Serpentinite in the next section. The interior uses of Chert include Decorative aggregates and Homes whereas the interior uses of Serpentinite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Chert and Serpentinite, they have various applications in construction industry. The uses of Chert in construction industry include Arrowheads, Construction aggregate, Cutting tool, Spear points and that of Serpentinite include As dimension stone, Cement manufacture, For road aggregate, Making natural cement.

More about Chert and Serpentinite

Here you can know more about Chert and Serpentinite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Chert and Serpentinite consists of mineral content and compound content. The mineral content of Chert includes Quartz, Silicon 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 Chert vs Serpentinite, the texture, color and appearance plays an important role in determining the type of rock. Chert is available in black, brown, green, grey, red, white colors whereas, Serpentinite is available in black, brown, colourless, green, grey, white colors. Appearance of Chert is Glassy or Pearly and that of Serpentinite is Rough and Dull. Properties of rock is another aspect for Chert vs Serpentinite. The hardness of Chert is 6.5-7 and that of Serpentinite is 3-5. The types of Chert are Flint, Jasper, Radiolarite, Common Chert, Chalcedony, Agate, Onyx, Opal, Magadi-type Chert, Porcelanite, Siliceous Sinter 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 Chert is white while that of Serpentinite is white, greenish white or grey. The specific heat capacity of Chert is 0.74 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.Chert is heat resistant, impact resistant, pressure resistant, wear resistant whereas Serpentinite is heat resistant.
