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.
A clastic rock.
Sandstone.
sedimentary
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.
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.
Sedimentary 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.
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.
Claystone, and shale are sedimentary rocks formed from lithified deposits of clay.
Sedimentary rock is the rock formed as a result of deposits from weathering and erosion. Sedimentary rock can be millions of years old.
