Coquina and Limestone are very similar. In fact, Coquina IS a type of limestone. Coquina is a very strong and sturdy rock. It was used by Spanish soliders to buid Fort Castillo de San Marcos located in Saint Augustine, Florida. It is also commonly formed of mostly seashells. Limestone has seashells and fossils in it.
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.
Acid rain can erode coquina and lime rocks by dissolving the calcium carbonate in the rocks, leading to the weakening and eventual breakdown of the rock structure. Over time, this process can degrade the coquina and lime rocks, causing them to deteriorate and lose their integrity.
A rock formed from crushed shells and coral is known as coquina. Coquina is a sedimentary rock that is composed of fragmented shell and coral debris cemented together. It is commonly found along coastlines and can have a characteristic porous appearance.
Limestone is commonly composed of the remains of animal shells, such as calcite from marine organisms like corals and mollusks. Over time, these shells accumulate and solidify into layers of rock.
marble used to be limestone
Coquina is a sedimentary rock made up of shells, shell fragments, and skeletons of small marine creatures.
They can, and do. Chalk and coquina are examples of limestone formed from skeletal or shell remains of marine organisms.
Limestones are sedimentary rocks made of skeletal remains. Limestones are recognizable because they react with Acid. Crystalline limestone are micro skeletons with large visible crystals. Micritic limestone is lithographic limestone and it is basically fine grained mud with micro-skeletons. Fossiliferous limestone is made with whole fossils in my experience mostly shells. Coquina is parts of skeletons pressed together. The difference between coquina and fossiliferous is that coquina doesn't have whole fossils. Lastly there is chalk. This is a lot of microorganisms remains pressed together.
classic rocks are not minerals. limestone is

I think you are describing a type of limestone called coquina.
Fossil rich limestone is limestone with various sea creature fossils in it such as shells. It is organic and fine grained. It is sedimentary... Yea that's it :P
Sedimentary rock formed by shells is called limestone. Limestone is primarily made up of calcium carbonate that is deposited by the accumulation and compaction of shell fragments and other organic remains.
Quicklime reacts with water, limestone doesn't. That's probably the fastest way.
