Formation. Turbidites are sediments which are transported and deposited by density flow, not by tractional or frictional flow. The distinction is that, in a normal river or stream bed, particles of rock are carried along by frictional drag of water on the particle (known as tractional flow ).

Marine limestone forms because seawater has high concentrations of two key dissolved chemicals-calcium (Ca ++) and bicarbonate (HCO 3-) ions. In the near-surface layer of most oceans, corals, clams, and other sea-dwelling creatures use these two chemicals to make protective shells by combining them to form calcite or "aragonite," which is the ...Marine Limestone.

Limestone is found in beds, and most limestone beds form in marine environments in which big deposits of organisms and carbonate precipitation build up over the years, like an ocean or large lake.
