Lherzolite vs Cataclasite


Cataclasite vs Lherzolite


Definition

Definition
Lherzolite is a type of ultramafic igneous rock which contains essential olivine and clinopyroxene and orthopyroxene in equal proportions  
Cataclasite is a type of cataclastic rock that is formed by fracturing and comminution during faulting. It is normally cohesive and non-foliated, consisting of angular clasts in a finer-grained matrix  

History
  
  

Origin
France  
Swiss Alps, Europe  

Discoverer

Etymology
From the Lherz Massif, an alpine peridotite complex, at Étang de Lers, near Massat in the French Pyrenees; Lherz is the archaic spelling of this location  
From the Italian word cataclasi

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.  
Cataclasiste rocks mainly form by pressure deep under the Earth's surface, from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

Lherzolite vs Cataclasite 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 Cataclasite Reserves. Lherzolite is a type of ultramafic igneous rock which contains essential olivine and clinopyroxene and orthopyroxene in equal proportions. Cataclasite is a type of cataclastic rock that is formed by fracturing and comminution during faulting. It is normally cohesive and non-foliated, consisting of angular clasts in a finer-grained matrix. 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 Cataclasite information and Lherzolite vs Cataclasite characteristics in the upcoming sections.

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 Cataclasite include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate.

More about Lherzolite and Cataclasite

Here you can know more about Lherzolite and Cataclasite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Lherzolite and Cataclasite consists of mineral content and compound content. The mineral content of Lherzolite includes Harzburgite, Olivine, Pyroxene, Pyrrhotite and mineral content of Cataclasite includes Albite, Apatite, Augite, Biotite, Calcite, Enstatite, Epidote, Feldspar, Micas, Muscovite or Illite, Pyroxene, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Lherzolite vs Cataclasite, 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, Cataclasite is available in brown, green, white, yellow colors. Appearance of Lherzolite is Glassy, Vesicular and Foilated and that of Cataclasite is Dull and Banded. Properties of rock is another aspect for Lherzolite vs Cataclasite. The hardness of Lherzolite is 6.5 and that of Cataclasite is 3-4. The types of Lherzolite are Garnet Lherzolite whereas types of Cataclasite are Protocataclasite, Mesocataclasite, Ultracataclasite and Foliated cataclasite. 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 Cataclasite is black. The specific heat capacity of Lherzolite is 0.95 kJ/Kg K and that of Cataclasite is 0.84 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 Cataclasite is heat resistant, impact resistant, pressure resistant.
