1.1 Definition

A water-soluble mineral sediment resulting from concentration and crystallization by evaporation from an aqueous solution

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

5.1 Formation

Evaporite is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.

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 Evaporite and Coquina Properties

Know all about Evaporite and Coquina properties here. All properties of rocks are important as they define the type of rock and its application. Evaporite and Coquina belong to Sedimentary Rocks.Texture of Evaporite is Earthy whereas that of Coquina is Clastic. Evaporite appears Glassy, Vesicular and Foilated and Coquina appears Layered, Banded, Veined and Shiny. The luster of Evaporite is subvitreous to dull while that of Coquina is dull to vitreous to submetallic. Evaporite is available in colourless, green, grey, silver, white colors whereas Coquina is available in beige, buff, orange colors. The commercial uses of Evaporite are used in the manufacture of ceramic powder, used in the preparation of sulfuric acid and silicon diborite and that of Coquina are creating artwork.
