Definition
A carbonate rock which is matrix supported and contains over 10% allochems in a carbonate mud 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

Archaeological Significance
Formation
Wackestone is a type of sedimentary rock formed when a river carries or transports pieces of broken rock as it flows. These particles settle down and are then compacted due to high temperature and pressure hence forming Wackestone.
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.

Wackestone 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. Wackestone vs Coquina characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Wackestone and Properties of Coquina. Learn more about Wackestone vs Coquina in the next section. The interior uses of Wackestone include Decorative aggregates, Flooring and Interior decoration whereas the interior uses of Coquina include Decorative aggregates, Homes, Hotels and Interior decoration. Due to some exceptional properties of Wackestone and Coquina, they have various applications in construction industry. The uses of Wackestone in construction industry include Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for the manufacture of mortar and that of Coquina include Building houses or walls, Construction aggregate.
More about Wackestone and Coquina
Here you can know more about Wackestone and Coquina. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Wackestone and Coquina consists of mineral content and compound content. The mineral content of Wackestone includes Biotite, Chlorite, Feldspar, Micas, Muscovite or Illite, Plagioclase, Pyrite, Quartz 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 Wackestone vs Coquina, the texture, color and appearance plays an important role in determining the type of rock. Wackestone is available in black, blue, brown, green, grey, orange, red, white, yellow colors whereas, Coquina is available in beige, buff, orange colors. Appearance of Wackestone is Rough and Dull and that of Coquina is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Wackestone vs Coquina. The hardness of Wackestone is 2-3 and that of Coquina is 1-2. The types of Wackestone are Marl, Shale and Argillite whereas types of Coquina are Sedimentary rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Wackestone and Coquina is white.
