An organic sedimentary rock composed of cemented shells is called limestone. Limestone is primarily made up of the mineral calcite, which is derived from the shells of marine organisms like coral and mollusks. Over time, these shells accumulate and compress to form solid rock.
Limestone in various forms such as chalk and coquina.
It is a carbonate sedimentary rock, composed of precipitated calcite or shells and shell fragments composed mainly of calcite, calcite being composed of CaCO3.
Shells of marine organisms are primarily composed of calcium carbonate, which is derived from minerals in seawater. The calcium carbonate can form various crystalline structures, such as calcite or aragonite, leading to different types of shells with varying levels of hardness and resilience. Additionally, shells may also contain proteins and other organic compounds that contribute to their strength and flexibility.

limestone
Limestone is a sedimentary rock composed of fragmented skeletons and shells of sea organisms. These fragments are compacted and cemented together over time to form the rock.
An organic sedimentary rock made of microscopic shells is called limestone. Limestone is mainly composed of calcium carbonate derived from the accumulation of marine organism shells such as shells of foraminifera, coral, and mollusks. Over time, these shells compact and cement together to form solid rock.
