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.

All about Wackestone and Coquina Properties
Know all about Wackestone and Coquina properties here. All properties of rocks are important as they define the type of rock and its application. Wackestone and Coquina belong to Sedimentary Rocks.Texture of Wackestone is Clastic whereas that of Coquina is Clastic. Wackestone appears Rough and Dull and Coquina appears Layered, Banded, Veined and Shiny. The luster of Wackestone is dull while that of Coquina is dull to vitreous to submetallic. Wackestone is available in black, blue, brown, green, grey, orange, red, white, yellow colors whereas Coquina is available in beige, buff, orange colors. The commercial uses of Wackestone are cemetery markers, pottery and that of Coquina are creating artwork.
