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.

More about Enderbite and Coquina
Here you can know more about Enderbite and Coquina. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Enderbite and Coquina consists of mineral content and compound content. The mineral content of Enderbite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Olivine, Plagioclase, Pyroxene, 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 Igneous Rocks. When we have to compare Enderbite vs Coquina, the texture, color and appearance plays an important role in determining the type of rock.
