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
Basaltic Trachyandesite is an extrusive igneous rock which is a type of Basalt rock and is formed by the rapid cooling of basaltic lava exposed at or very near the Earth's surface
Origin
Swiss Alps, Europe

Features
Easily splits into thin plates, Is one of the oldest rock
Has High structural resistance against erosion and climate, Very fine grained rock
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.
Basaltic Trachandesite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.

Cataclasite vs Basaltic Trachyandesite 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 Basaltic Trachyandesite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Cataclasite and Properties of Basaltic Trachyandesite. Learn more about Cataclasite vs Basaltic Trachyandesite in the next section. The interior uses of Cataclasite include Decorative aggregates and Homes whereas the interior uses of Basaltic Trachyandesite include Floor tiles, Homes, Hotels and Kitchens. Due to some exceptional properties of Cataclasite and Basaltic Trachyandesite, 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 Basaltic Trachyandesite include As dimension stone, Cobblestones, Rail track ballast, Roadstone.
More about Cataclasite and Basaltic Trachyandesite
Here you can know more about Cataclasite and Basaltic Trachyandesite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Cataclasite and Basaltic Trachyandesite 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 Basaltic Trachyandesite includes Olivine, Plagioclase, Pyroxene. You can also check out the list of all Metamorphic Rocks. When we have to compare Cataclasite vs Basaltic Trachyandesite, 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, Basaltic Trachyandesite is available in black, brown, light to dark grey colors. Appearance of Cataclasite is Dull and Banded and that of Basaltic Trachyandesite is Dull and Soft. Properties of rock is another aspect for Cataclasite vs Basaltic Trachyandesite. The hardness of Cataclasite is 3-4 and that of Basaltic Trachyandesite is 6. The types of Cataclasite are Protocataclasite, Mesocataclasite, Ultracataclasite and Foliated cataclasite whereas types of Basaltic Trachyandesite are Alkaline Basalt, Boninite, High Alumina Basalt, Mid Ocean Ridge Basalt (MORB), Tholeiitic Basalt, Basaltic trachyandesite, Mugearite and Shoshonite. 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 Basaltic Trachyandesite is white to grey. The specific heat capacity of Cataclasite is 0.84 kJ/Kg K and that of Basaltic Trachyandesite is 0.84 kJ/Kg K.
