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.

Wehrlite 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.

Serpentinite vs Wehrlite 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 Wehrlite 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'.. Wehrlite is an ultramafic and ultrabasic rock that is a mixture of olivine and clinopyroxene. It is a subdivision of the peridotites. 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 Wehrlite information and Serpentinite vs Wehrlite characteristics in the upcoming sections.

The uses of Serpentinite in construction industry include As dimension stone, Cement manufacture, For road aggregate, Making natural cement and that of Wehrlite include As dimension stone, Cobblestones.

More about Serpentinite and Wehrlite

Here you can know more about Serpentinite and Wehrlite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Serpentinite and Wehrlite consists of mineral content and compound content. The mineral content of Serpentinite includes Carbonate, Magnetite, Pyrrhotite, Serpentine, Sulfides and mineral content of Wehrlite includes Pyroxene. You can also check out the list of all Metamorphic Rocks. When we have to compare Serpentinite vs Wehrlite, the texture, color and appearance plays an important role in determining the type of rock. Serpentinite is available in black, brown, green, grey, white colors whereas, Wehrlite is available in dark greenish - grey, green colors. Appearance of Serpentinite is Rough and Dull and that of Wehrlite is Rough and Banded. Properties of rock is another aspect for Serpentinite vs Wehrlite. The hardness of Serpentinite is 3-5 and that of Wehrlite is 5.5-6. The types of Serpentinite are Jadeitite whereas types of Wehrlite are Ultramafic rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Serpentinite and Wehrlite is white, greenish white or grey. The specific heat capacity of Serpentinite is 0.95 kJ/Kg K and that of Wehrlite is 0.63 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 Wehrlite is heat resistant, impact resistant, pressure resistant.
