Definition
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
Sovite is a coarse-grained variety of carbonatite which belongs to intrusive igneous rock

Archaeological Significance
Formation
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.
Sovites are formed due to low degrees of partial melting of rocks.

All about Coquina and Sovite Properties
Know all about Coquina and Sovite properties here. All properties of rocks are important as they define the type of rock and its application. Coquina belongs to Sedimentary Rocks while Sovite belongs to Igneous Rocks.Texture of Coquina is Clastic whereas that of Sovite is Granular, Poikiloblastic. Coquina appears Layered, Banded, Veined and Shiny and Sovite appears Dull, Banded and Foilated. The luster of Coquina is dull to vitreous to submetallic while that of Sovite is subvitreous to dull. Coquina is available in beige, buff, orange colors whereas Sovite is available in black, brown, green, grey, pink, white colors. The commercial uses of Coquina are creating artwork and that of Sovite are an oil and gas reservoir, as a feed additive for livestock, creating artwork, gemstone, metallurgical flux, production of lime, soil conditioner, source of magnesia (mgo).
