Archaeological Significance
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.

All about Enderbite and Coquina Properties
Know all about Enderbite and Coquina properties here. All properties of rocks are important as they define the type of rock and its application. Enderbite belongs to Igneous Rocks while Coquina belongs to Sedimentary Rocks.Texture of Enderbite is Granular whereas that of Coquina is Clastic. Enderbite appears Veined or Pebbled and Coquina appears Layered, Banded, Veined and Shiny. The luster of Enderbite is while that of Coquina is dull to vitreous to submetallic. Enderbite is available in black, grey, orange, pink, white colors whereas Coquina is available in beige, buff, orange colors. The commercial uses of Enderbite are curling, gemstone, laboratory bench tops, tombstones and that of Coquina are creating artwork.
