Though coquina rock is relatively low density and soft, it does not float. Smaller pieces are often broken and washed around by waves.

No, coquina is not a metamorphic rock. It is a sedimentary rock formed from compressed shells and sand. Metamorphic rocks undergo changes in texture and mineral composition due to high pressure and temperature, which is not the case for coquina.
No, coquina is not foliated. Coquina is a sedimentary rock composed of loosely cemented fragments of shells and coral. Foliation typically occurs in metamorphic rocks, where minerals are aligned in layers or bands.
A rock made entirely of seashell fragments is known as a coquina. Coquina rocks are formed from the accumulation and compression of broken seashells, creating a unique and porous sedimentary rock that is often found along coastal regions.

It is a Coquina mine. Coquina is a sedimentary rock used primarily as a base for highway construction I Where is it all comming from ? ?
Coquina is a sedimentary rock composed of loosely cemented shells and shell fragments, while limestone is a sedimentary rock made up primarily of calcite and aragonite minerals. Limestone is typically harder and more dense than coquina, which is softer and more porous due to its shell content.

Well, isn't that an interesting question! If a coquina rock were exposed to high temperatures and pressure, it would undergo a transformation. Over time, the heat and pressure would cause the minerals in the rock to recrystallize and form a new type of rock called marble. It's like nature's way of creating something beautiful out of a little bit of pressure and heat.
Coquina can come in various colors, including white, beige, yellow, and pink. The color of coquina is determined by the type of shells and minerals present in the sediment that make up the rock.
Coquina is the sedimentary rock most likely to contain visible fossils.
