What environment does limestone form in
Limestone is formed in shallow, calm, marine water. This environment means that organism are capable of creating calcium carbonate shells. When they die, their shells and micro skeletons are deposited on the ocean floor. As the sediment builds up, the weight and pressure of the sediment above compresses the lower sediment into a solid rock.Mar 3, 2023 · Limestone, primarily consists of the mineral calcite and, forms in multiple depositional environments. Typical environments include hot springs, lakes and coral reefs in the tropical oceans. However, the most dominant depositional environment of limestone is shallow waters of tropical seas, where carbonate-shelled plants and animals proliferate.

stromatolite, layered deposit, mainly of limestone, formed by the growth of blue-green algae (primitive one-celled organisms). These structures are usually characterized by thin, alternating light and dark layers that may be flat, hummocky, or dome-shaped. The alternating layers are largely produced by the trapping of sediment washed up during ...Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism.
