A rock formed from deposits of shell fragment is Limestone.
Limestone is a common sedimentary rock formed from the accumulation of shell fragments, coral, and other marine organisms. Over time, these organic materials can become compressed and cemented together to create a solid rock formation.
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.
Sandstone.
A clastic rock.
Limestone. However most large masses of limestone formed from coral reefs, not shells. The shell fossils in this limestone are "incidentals" due to shell dwelling organisms living on the periphery of the reef, not the bulk of the limestone.
sedimentary
Limestone is a rock formed from the accumulation of calcium carbonate derived from the remains of sea shells and marine organisms. Over time, these sedimentary deposits can become compressed and cemented to form solid rock.
Coquina is classified as an organic rock because it is composed of fragments of shells that come from animals like mollusks. Its texture is rough and granular due to the big shell-like particles.
Sedimentary rock
The particles in shell limestone are primarily fragments, specifically the remains of shell material from marine organisms such as mollusks and corals. These fragments are typically composed of calcium carbonate and can vary in size and shape. Over time, these shell fragments accumulate and undergo lithification, forming the cohesive rock known as shell limestone.
A sedimentary rock is formed when rock fragments are compacted and cemented together by pressure and minerals. Examples of sedimentary rocks include sandstone, shale, and conglomerate.
Sedimentary rock is the rock formed as a result of deposits from weathering and erosion. Sedimentary rock can be millions of years old.
