WebDiagenesis includes the many post-depositional processes that alter a sediment to a rock, a sand to a sandstone. The term diagenesis was coined in 1888 by von Gümbel (p. 334) and has been used in many senses since then. A complete review of the subject, its history, and its terminology has been given by Dunoyer de Segonzac (1968).
