N2  - As an example of an epeiric carbonate ramp depositional system, the world-class outcrops of the Middle Jurassic Dhruma Formation were studied in the Oman Mountains (Sultanate of Oman). An integrated approach was followed: facies analyses were combined with quantitative sequence-stratigraphic methods as well as bio- and chemostratigraphy. Depositional environments range from peritidal to lagoonal and â??shoal-likeâ?? environments. A conspicuous four-level hierarchy of cyclicity was identified. This is substantiated by facies trends and specific cycle indicators such as various types of discontinuity surfaces, biofacies changes, and a suite of quantitative- and semi-quantitative sequence-stratigraphic methods like facies stacking pattern plots, facies percentage, bed-thickness and bio-component diversity plots, as well as diagrams representing the environmental range and facies belt width per high-frequency sequence. Potential reservoir facies are present in the form of peloidal and oolitic grainstones; potential baffle/seal facies as vastly extensive mudstones and marls. A transition from peritidal to low-energy lagoonal deposits to increasingly high-energy deposits can be observed towards the top of the Dhruma Formation representing a landward shift of the depositional environment. This study may be useful as outcrop analogue for the hydrocarbon-bearing parts of the Dhruma in the subsurface of the Arabian Plate and for similar epeiric carbonates elsewhere. © 2017 The Authors.
