Definition
Conglomerate is a sedimentary rock which forms from rounded gravel and boulder sized clasts which are cemented together in a 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

Formation
Conglomerate forms where sediments consisting mainly of pebble and cobble-size clasts at least two millimeters in diameter starts accumulating.
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 Conglomerate and Coquina Properties
Know all about Conglomerate and Coquina properties here. All properties of rocks are important as they define the type of rock and its application. Conglomerate and Coquina belong to Sedimentary Rocks.Texture of Conglomerate is Clastic whereas that of Coquina is Clastic. Conglomerate appears Shiny and Rounded and Coquina appears Layered, Banded, Veined and Shiny. The luster of Conglomerate is dull while that of Coquina is dull to vitreous to submetallic. Conglomerate and Coquina are available in beige, black, brown, buff, light to dark grey, orange, rust, white, yellow colors. The commercial uses of Conglomerate are cemetery markers, in aquifers, tombstones and that of Coquina are creating artwork.
