Definition
Shoshonite is a basaltic rock, properly a potassic trachyandesite, composed of olivine, augite and plagioclase phenocrysts in a groundmass with calcic plagioclase and sanidine and some dark-colored volcanic glass
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

Archaeological Significance
Formation
Shoshonite 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.

Shoshonite 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. Shoshonite vs Cataclasite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Shoshonite and Properties of Cataclasite. Learn more about Shoshonite vs Cataclasite in the next section. The interior uses of Shoshonite include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Cataclasite include Decorative aggregates and Homes. Due to some exceptional properties of Shoshonite and Cataclasite, they have various applications in construction industry. The uses of Shoshonite in construction industry include As dimension stone, Cobblestones, Rail track ballast, Roadstone and that of Cataclasite include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate.
More about Shoshonite and Cataclasite
Here you can know more about Shoshonite and Cataclasite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Shoshonite and Cataclasite consists of mineral content and compound content. The mineral content of Shoshonite includes Pyroxene 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 Shoshonite vs Cataclasite, the texture, color and appearance plays an important role in determining the type of rock. Shoshonite is available in brown- black, dark brown colors whereas, Cataclasite is available in brown, green, white, yellow colors. Appearance of Shoshonite is Dull and that of Cataclasite is Dull and Banded. Properties of rock is another aspect for Shoshonite vs Cataclasite. The hardness of Shoshonite is 6 and that of Cataclasite is 3-4. The types of Shoshonite are Intermediate volcanic rock 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 Shoshonite is white to grey while that of Cataclasite is black. The specific heat capacity of Shoshonite is 0.79 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.Shoshonite is heat resistant, pressure resistant whereas Cataclasite is heat resistant, impact resistant, pressure resistant.
