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.
Pyrolite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

Chalk vs Pyrolite 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 Pyrolite Reserves. Chalk is a soft, white, powdery limestone consisting mainly of fossil shells of foraminifers. Pyrolite is an igneous rock consisting of about three parts of peridotite and one part of basalt. 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 Pyrolite information and Chalk vs Pyrolite characteristics in the upcoming sections.

Chalk vs Pyrolite 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 Pyrolite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Chalk and Properties of Pyrolite. Learn more about Chalk vs Pyrolite in the next section. The interior uses of Chalk include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Pyrolite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Chalk and Pyrolite, 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 Pyrolite include As dimension stone, Cobblestones.

More about Chalk and Pyrolite

Here you can know more about Chalk and Pyrolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Chalk and Pyrolite consists of mineral content and compound content. The mineral content of Chalk includes Calcite, Clay, Clay Minerals, Quartz, Sand and mineral content of Pyrolite includes Amphibole, Chromite, Garnet, Magnesium, Olivine, Phlogopite, Plagioclase, Pyroxene. You can also check out the list of all Sedimentary Rocks. When we have to compare Chalk vs Pyrolite, the texture, color and appearance plays an important role in determining the type of rock. Chalk is available in grey, white, yellow colors whereas, Pyrolite is available in dark greenish - grey colors. Appearance of Chalk is Soft and that of Pyrolite is Rough and Shiny. Properties of rock is another aspect for Chalk vs Pyrolite. The hardness of Chalk is 1 and that of Pyrolite is 5.5-6. The types of Chalk are Not Available whereas types of Pyrolite are Dunite, Wehrlite, Harzburgite, Lherzolite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Chalk and Pyrolite is white. The specific heat capacity of Chalk is 0.90 kJ/Kg K and that of Pyrolite is 1.25 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 Pyrolite is heat resistant, pressure resistant, wear resistant.
