5 Formation

5.1 Formation

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 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.

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

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

More about Serpentinite and Chert

Here you can know more about Serpentinite and Chert. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Serpentinite and Chert consists of mineral content and compound content. The mineral content of Serpentinite includes Carbonate, Magnetite, Pyrrhotite, Serpentine, Sulfides and mineral content of Chert includes Quartz, Silicon. You can also check out the list of all Metamorphic Rocks. When we have to compare Serpentinite vs Chert, the texture, color and appearance plays an important role in determining the type of rock. Serpentinite is available in black, brown, colourless, green, grey, white colors whereas, Chert is available in black, brown, green, grey, red, white colors. Appearance of Serpentinite is Rough and Dull and that of Chert is Glassy or Pearly. Properties of rock is another aspect for Serpentinite vs Chert. The hardness of Serpentinite is 3-5 and that of Chert is 6.5-7. The types of Serpentinite are Jadeitite whereas types of Chert are Flint, Jasper, Radiolarite, Common Chert, Chalcedony, Agate, Onyx, Opal, Magadi-type Chert, Porcelanite, Siliceous Sinter. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Serpentinite and Chert is white, greenish white or grey. The specific heat capacity of Serpentinite is 0.95 kJ/Kg K and that of Chert is 0.74 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Serpentinite is heat resistant whereas Chert is heat resistant, impact resistant, pressure resistant, wear resistant.
