Definition
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
Lherzolite is a type of ultramafic igneous rock which contains essential olivine and clinopyroxene and orthopyroxene in equal proportions
Origin
Swiss Alps, Europe

Etymology
From the Italian word cataclasi
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

Archaeological Significance
Formation
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 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.

Cataclasite vs Lherzolite 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. Cataclasite vs Lherzolite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Cataclasite and Properties of Lherzolite. Learn more about Cataclasite vs Lherzolite in the next section. The interior uses of Cataclasite include Decorative aggregates and Homes whereas the interior uses of Lherzolite include Decorative aggregates, Entryways, Homes and Interior decoration. Due to some exceptional properties of Cataclasite and Lherzolite, they have various applications in construction industry. The uses of Cataclasite in construction industry include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate and that of Lherzolite include Landscaping, Manufacture of magnesium and dolomite refractories, Used for flooring, stair treads, borders and window sills..
More about Cataclasite and Lherzolite
Here you can know more about Cataclasite and Lherzolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Cataclasite and Lherzolite consists of mineral content and compound content. The mineral content of Cataclasite includes Albite, Apatite, Augite, Biotite, Calcite, Enstatite, Epidote, Feldspar, Micas, Muscovite or Illite, Pyroxene, Quartz and mineral content of Lherzolite includes Harzburgite, Olivine, Pyroxene, Pyrrhotite. You can also check out the list of all Metamorphic Rocks. When we have to compare Cataclasite vs Lherzolite, the texture, color and appearance plays an important role in determining the type of rock. Cataclasite is available in brown, green, white, yellow colors whereas, Lherzolite is available in black, dark greenish - grey, green, pink, purple colors. Appearance of Cataclasite is Dull and Banded and that of Lherzolite is Glassy, Vesicular and Foilated. Properties of rock is another aspect for Cataclasite vs Lherzolite. The hardness of Cataclasite is 3-4 and that of Lherzolite is 6.5. The types of Cataclasite are Protocataclasite, Mesocataclasite, Ultracataclasite and Foliated cataclasite whereas types of Lherzolite are Garnet Lherzolite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Cataclasite is black while that of Lherzolite is white. The specific heat capacity of Cataclasite is 0.84 kJ/Kg K and that of Lherzolite 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.Cataclasite is heat resistant, impact resistant, pressure resistant whereas Lherzolite is heat resistant, impact resistant, pressure resistant, wear resistant.
