Abstract:
Intrashelf basins occurring on epeiric carbonate platforms are commonly associated with the presence of excellent carbonate source rocks, and because they often border potential carbonate reservoirs updip, they may form the core of rich petroleum systems. This is a common phenomenon of many Mesozoic hydrocarbon plays in the Middle East. Despite this fact, studies investigating intrashelf-basinal, fine-grained carbonates are rare, because it is assumed that little lithofacies variability is present in these successions as a consequence of their relatively homogeneous appearance where they are sampled in core or visited in exposures. Those that have been performed mostly lack process-detail analyses, and interpret the organic-carbon enrichment in these sediments to be simply a function of either occurrence of localised bottom-water anoxia or high primary organic production under low-energy conditions, dominated by suspension-settling events.
