Carbon dating of seashells have indicated that the terraces range between 1800 - 5600 years old and it was deposited from deep marine turbidity currents.Petroleum trap (Redirected from Structural trap) Fault trap In petroleum geology, a trap is a geological structure affecting the reservoir rock and caprock of a petroleum system allowing the accumulation of hydrocarbons in a reservoir. Traps can be of two types: stratigraphic or structural.Valmeyer Anticline, O'Fallon Fault Paralleling the Eureka-House Springs structure and approxi­ mately 12 mi to the northeast is the Valmeyer anticline. In Missouri, this structure is poorly exposed, but it has moderate subsurface expression with as much as 100ft of structural relief, down to the southwest (see cross section B-B').These faults tend to form subparallel arrays where there are flexures or jogs on the first-order faults (Fig. 4). Worldwide, such accommodation fault arrays tend to be at ∼70° to the local trend of the first-order structures and rock sequences.

The most common type of structural trap is formed by an anticline, a structure with a concave (as viewed from below) ... Here, the fracture and slippage of rock along a fault line may bring an impermeable stratum in contact with a layer of permeable reservoir rock and thus forms a barrier to petroleum migration.Structural traps are primarily the result of folding and (or) faulting, or both. 1. Anticlinal (fold) and dome traps. Necessary conditions: An impervious cap rock and a porous reservoir rock ...Fault throw analysis shows that below 1800 ms, the major faults with large fault throws act as hydrocarbon migration pathways, while above 1 800 ms, faults with small throws act as seals of hydrocarbon traps. There are four-way dip rollover anticlines and three-way downdip traps created by the minor faults. ... rollover anticline. fault seal.strike slip fault.
