The diagenetic history of Cadeby Formation carbonate (EZ1 Ca), Upper Permian, eastern England

G. M. Harwood

Department of Geology, The University of Newcastle upon Tyne, Newcastle upon Tyne NE1 7RU

The Upper Permian Cadeby Formation (formerly the Lower Magnesian Limestone) crops out from North Yorkshire to Nottinghamshire in eastern England. The Cadeby Formation comprises shallow water carbonates within which penecontemporaneous, eogenetic, mesogenetic and teleogenetic diagenetic events can be defined. Penecontemporaneous events included facies-controlled dolomitization and evaporite calcitization. Pervasive dolomitization, largely independent of facies, was eogenetic. Late eogenetic to early mesogenetic events were dominated by replacive and pore-filling anhydrite crystallization. Both pervasive dolomitization and subsequent anhydrite formation occluded porosity. Other mesogenetic events were of local effect only. Anhydrite to gypsum transformation, together with evaporite dissolution and carbonate leaching, dominate the later near-surface, or telogenetic, events.
