Anorthosite vs Cataclasite


Cataclasite vs Anorthosite


Definition

Definition
Anorthosite is a granular igneous rock composed largely of labradorite or plagioclase  
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

Formation

Formation
Anorthosite is a phaneritic, intrusive igneous rock which is characterized by a predominance of plagioclase feldspar which is almost 90–100%, and a minimal mafic component.   
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.

Anorthosite 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 Anorthosite and Cataclasite Reserves. Anorthosite is a granular igneous rock composed largely of labradorite or plagioclase. 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 Anorthosite vs Cataclasite information and Anorthosite vs Cataclasite characteristics in the upcoming sections.

Anorthosite vs Cataclasite 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. Anorthosite vs Cataclasite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Anorthosite and Properties of Cataclasite. Learn more about Anorthosite vs Cataclasite in the next section. The interior uses of Anorthosite include Decorative aggregates, Floor tiles, Homes and Interior decoration whereas the interior uses of Cataclasite include Decorative aggregates and Homes. Due to some exceptional properties of Anorthosite and Cataclasite, they have various applications in construction industry. The uses of Anorthosite in construction industry include As dimension stone, Cement manufacture, For road aggregate and that of Cataclasite include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate.

More about Anorthosite and Cataclasite

Here you can know more about Anorthosite and Cataclasite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Anorthosite and Cataclasite consists of mineral content and compound content. The mineral content of Anorthosite includes Amphibole, Clinopyroxene, Ilmenite, Magnetite, Olivine, Orthopyroxene 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 Anorthosite vs Cataclasite, the texture, color and appearance plays an important role in determining the type of rock. Anorthosite is available in black, bluish - grey, brown, green, grey, light greenish grey, pink, white colors whereas, Cataclasite is available in brown, green, white, yellow colors. Appearance of Anorthosite is Layered, Banded, Veined and Shiny and that of Cataclasite is Dull and Banded. Properties of rock is another aspect for Anorthosite vs Cataclasite. The hardness of Anorthosite is 5-6 and that of Cataclasite is 3-4. The types of Anorthosite are Proterozoic Anorthosite and Archean Anorthosite 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 Anorthosite is white while that of Cataclasite is black. The specific heat capacity of Anorthosite is 0.84 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.Anorthosite is heat resistant, impact resistant, pressure resistant, scratch resistant, wear resistant whereas Cataclasite is heat resistant, impact resistant, pressure resistant.
