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
Foidolite is a rare type of coarse-grained intrusive igneous rock with a feldspathoid mineral content greater than 60%

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.
Foidolites 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 Foidolite 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 Foidolite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Cataclasite and Properties of Foidolite. Learn more about Cataclasite vs Foidolite in the next section. The interior uses of Cataclasite include Decorative aggregates and Homes whereas the interior uses of Foidolite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Cataclasite and Foidolite, 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 Foidolite include As dimension stone, Cement manufacture, For road aggregate.
More about Cataclasite and Foidolite
Here you can know more about Cataclasite and Foidolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Cataclasite and Foidolite 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 Foidolite includes Amphibole, Biotite, Feldspar, Olivine, Plagioclase, Pyroxene. You can also check out the list of all Metamorphic Rocks. When we have to compare Cataclasite vs Foidolite, 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, Foidolite is available in black, brown, green, grey, pink, white colors. Appearance of Cataclasite is Dull and Banded and that of Foidolite is Dull. Properties of rock is another aspect for Cataclasite vs Foidolite. The hardness of Cataclasite is 3-4 and that of Foidolite is 1.5. The types of Cataclasite are Protocataclasite, Mesocataclasite, Ultracataclasite and Foliated cataclasite whereas types of Foidolite are Igneous rock. 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 Foidolite is white. The specific heat capacity of Cataclasite is 0.84 kJ/Kg K and that of Foidolite is 0.79 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 Foidolite is heat resistant, wear resistant.
