BUILDING A CONCEPTUAL MODEL
The Middle Cretaceous outcrop belts of Oman and the Zagros Mountains provide an opportunity to study this stratigraphic interval in detail , and build a reference model that can be applied through the subsurface and across the plate ( Homewood et al ., 2008 ; Razin et al ., 2017 ). These outcrops provide valuable reference
sections , where sequence stratigraphic surfaces can be identified and age constrained . They also provide the opportunity to study sedimentology , establish depositional facies , and characterize depositional morphology . The depositional sequences established at outcrop can then be tied to nearby subsurface wells and seismic lines .
