Much or most of the carbonate is generated when organisms extract it from sea water to form their skeletons, although some, mainly micrites, may ... The depositional environment can be characterized by it’s levels of oxygenation and energy. A high-energy environment is one in which the water is fast-moving and agitated, able to carry particles of large grain sizes; typically this occurs in shallow lakes & seas and in rivers, as well as deserts.
