Definition
Enderbite rock is an igneous rock which belongs to the Charnockite rock series
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
Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.
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.
