The Kenilworth Member of the Blackhawk Formation (Upper Cretaceous, Campanian) is nearly continuously exposed from Price to Hatch Mesa in the Book Cliffs, Utah. Five main depositional environments are recognized: coastal plain, foreshore and upper shoreface, lower shoreface, inner shelf, and incised valley-fill deposits. The shelf-to-shoreface deposits combine to form nine coarsening-upward, wave- to storm-dominated parasequences that are 7-32 m thick, and that split basinward into smaller coarsening-upward succession or bedsets that are 2-18 m thick. A maximum of four bedsets occurs within an individual parasequence. Bedset bounding surfaces are occasionally marked by thoroughly bioturbated, iron-rich carbonate-cemented sandstones within the parasequences. In the subsurface, similar bedset bounding surfaces may act as permeability barriers or baffles, leading to reservoir compartmentalization.
