Serpentinite vs Lherzolite


Definition

Definition
Lherzolite is a type of ultramafic igneous rock which contains essential olivine and clinopyroxene and orthopyroxene in equal proportions  
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'.

Formation

Formation
Lherzolite 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.  
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.

Lherzolite 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 Lherzolite and Serpentinite Reserves. Lherzolite is a type of ultramafic igneous rock which contains essential olivine and clinopyroxene and orthopyroxene in equal proportions. 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 Lherzolite vs Serpentinite information and Lherzolite vs Serpentinite characteristics in the upcoming sections.

Lherzolite 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. Lherzolite vs Serpentinite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Lherzolite and Properties of Serpentinite. Learn more about Lherzolite vs Serpentinite in the next section. The interior uses of Lherzolite include Decorative aggregates, Entryways, Homes and Interior decoration whereas the interior uses of Serpentinite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Lherzolite and Serpentinite, they have various applications in construction industry. The uses of Lherzolite in construction industry include Landscaping, Manufacture of magnesium and dolomite refractories, Used for flooring, stair treads, borders and window sills. and that of Serpentinite include As dimension stone, Cement manufacture, For road aggregate, Making natural cement.

More about Lherzolite and Serpentinite

Here you can know more about Lherzolite and Serpentinite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Lherzolite and Serpentinite consists of mineral content and compound content. The mineral content of Lherzolite includes Harzburgite, Olivine, Pyroxene, Pyrrhotite and mineral content of Serpentinite includes Carbonate, Magnetite, Pyrrhotite, Serpentine, Sulfides. You can also check out the list of all Igneous Rocks. When we have to compare Lherzolite vs Serpentinite, the texture, color and appearance plays an important role in determining the type of rock. Lherzolite is available in black, dark greenish - grey, green, pink, purple colors whereas, Serpentinite is available in black, brown, green, grey, white colors. Appearance of Lherzolite is Glassy, Vesicular and Foilated and that of Serpentinite is Rough and Dull. Properties of rock is another aspect for Lherzolite vs Serpentinite. The hardness of Lherzolite is 6.5 and that of Serpentinite is 3-5. The types of Lherzolite are Garnet Lherzolite 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 Lherzolite is white while that of Serpentinite is white, greenish white or grey. The specific heat capacity of Lherzolite is 0.95 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.Lherzolite is heat resistant, impact resistant, pressure resistant, wear resistant whereas Serpentinite is heat resistant.
