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
Coquina is a sedimentary rock that is composed either wholly or almost entirely of the transported, abraded, and mechanically-sorted fragments of the shells of molluscs, trilobites, brachiopods, or other invertebrates
Origin
Swiss Alps, Europe
European Foreland Basins

From the Italian word cataclasi
From Concha (Latin)+ Coquina(Spanish) +conch(English)= Couquina (mid 19th century)

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.
Coquina is a sedimentary rock which is formed when billions of small clam-like seashell, called Coquina, or cockleshell are die and hence are deposited, buried and turns into a rock when pressure is applied.

Cataclasite vs Coquina 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 Coquina characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Cataclasite and Properties of Coquina. Learn more about Cataclasite vs Coquina in the next section. The interior uses of Cataclasite include Decorative aggregates and Homes whereas the interior uses of Coquina include Decorative aggregates, Homes, Hotels and Interior decoration. Due to some exceptional properties of Cataclasite and Coquina, 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 Coquina include Building houses or walls, Construction aggregate.
More about Cataclasite and Coquina
Here you can know more about Cataclasite and Coquina. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock.
