Figure 15. Distribution of the Upper Jurassic synrift plays and their associated extensional fault systems. Deflation of the North Sea dome leads to the shallow-marine depositional systems backstepping to concentrate the fairways in the Witch Ground graben and South Halibut Basins of the Outer Moray Firth, southern parts of the Viking Graben (including the Beryl embayment), and in and on the margins of the Central Graben and Horda platform. The onset on major rifting subsequently leads to the development of basin-margin submarine fan aprons in the South Viking Graben and the erosion of footwall highs in the East Shetland Basin. Many of the tilted fault blocks of the Brent province develop shoreline clastic fringes to an island archipelago and deep-water turbidite reservoir sandstones on their dip-slopes and neighboring hanging-wall depocenters.
