Definition
Basanite is a black basaltic rock which mainly contains plagioclase, augite, olivine and nepheline and is formerly used as a touchstone
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
Basanite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.
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.

Basanite vs Coquina Characteristics
Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Basanite vs Coquina characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Basanite and Properties of Coquina. Learn more about Basanite vs Coquina in the next section. The interior uses of Basanite include Decorative aggregates and Homes whereas the interior uses of Coquina include Decorative aggregates, Homes, Hotels and Interior decoration. Due to some exceptional properties of Basanite and Coquina, they have various applications in construction industry. The uses of Basanite in construction industry include Arrowheads, Construction aggregate, Cutting tool, Spear points and that of Coquina include Building houses or walls, Construction aggregate.
More about Basanite and Coquina
Here you can know more about Basanite and Coquina. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Basanite and Coquina consists of mineral content and compound content. The mineral content of Basanite includes Augite, Feldspar, Ilmenite, Olivine, Plagioclase 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 Basanite vs Coquina, the texture, color and appearance plays an important role in determining the type of rock.
