Definition
A sedimentary rock, deposit of a submarine turbidity currents and are composed of layered particles
  
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

Formation
Turbidite is a type of sedimentary rock formed when a river carries or transports pieces of broken rock as it flows. These particles then settle down and are subjected to high temperature and pressures hence forming Turbidite.
  
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.

Turbidite 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. Turbidite vs Coquina characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Turbidite and Properties of Coquina. Learn more about Turbidite vs Coquina in the next section. The interior uses of Turbidite include Bathrooms, Countertops, Decorative aggregates, Flooring, Homes and Interior decoration whereas the interior uses of Coquina include Decorative aggregates, Homes, Hotels and Interior decoration. Due to some exceptional properties of Turbidite and Coquina, they have various applications in construction industry. The uses of Turbidite in construction industry include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Making natural cement and that of Coquina include Building houses or walls, Construction aggregate.
More about Turbidite and Coquina
Here you can know more about Turbidite and Coquina. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Turbidite and Coquina consists of mineral content and compound content. The mineral content of Turbidite includes Coesite, Quartz, Sand and mineral content of Coquina includes Apatite, Augite, Bronzite, Calcite, Chert, Chlorite, Clay Minerals, Epidote, Feldspar, Garnet, Micas, Muscovite or Illite. You can also check out the list of all Sedimentary Rocks. When we have to compare Turbidite vs Coquina, the texture, color and appearance plays an important role in determining the type of rock. Turbidite is available in black, brown, colourless, green, grey, pink colors whereas, Coquina is available in beige, buff, orange colors. Appearance of Turbidite is Dull and Banded and that of Coquina is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Turbidite vs Coquina. The hardness of Turbidite is 3 and that of Coquina is 1-2. The types of Turbidite are Not Available whereas types of Coquina are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Turbidite and Coquina is white, greenish white or grey. The specific heat capacity of Turbidite is 0.92 kJ/Kg K and that of Coquina is Not Available. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Turbidite is heat resistant whereas Coquina is heat resistant, impact resistant, pressure resistant, wear resistant.
