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

Etymology
From Latin conglomeratus, to roll together, i.e. from com together + glomerare to gather into a ball, from glomus (genitive glomeris) a ball
  
From Concha (Latin)+ Coquina(Spanish) +conch(English)= Couquina (mid 19th century)

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.

Conglomerate 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. Conglomerate vs Coquina characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Conglomerate and Properties of Coquina. Learn more about Conglomerate vs Coquina in the next section. The interior uses of Conglomerate include Decorative aggregates, Floor tiles and Homes whereas the interior uses of Coquina include Decorative aggregates, Homes, Hotels and Interior decoration. Due to some exceptional properties of Conglomerate and Coquina, they have various applications in construction industry. The uses of Conglomerate in construction industry include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Roadstone and that of Coquina include Building houses or walls, Construction aggregate.
More about Conglomerate and Coquina
Here you can know more about Conglomerate and Coquina. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Conglomerate and Coquina consists of mineral content and compound content. The mineral content of Conglomerate includes Clay, Sand, Silica, Silt 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 Sedimentary Rocks. When we have to compare Conglomerate vs Coquina, the texture, color and appearance plays an important role in determining the type of rock. Conglomerate is available in beige, black, brown, buff, light to dark grey, orange, rust, white, yellow colors whereas, Coquina is available in beige, buff, orange colors. Appearance of Conglomerate is Shiny and Rounded and that of Coquina is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Conglomerate vs Coquina. The hardness of Conglomerate is 2-3 and that of Coquina is 1-2. The types of Conglomerate are Not Available whereas types of Coquina are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Conglomerate and Coquina is white. The specific heat capacity of Conglomerate is 0.92 kJ/Kg K and that of Coquina is Not Available. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Conglomerate is heat resistant whereas Coquina is heat resistant, impact resistant, pressure resistant, wear resistant.
