* [[Porosity]] in the sequence tops plugged by caliche and vadose fibrous cements
* [[Porosity]] in the sequence tops plugged by caliche and vadose fibrous cements
* [[Porosity]] in subtidal grainy parts of sequences generally lacks early sparry cements; primary porosity preserved where marine fringing cement present
* [[Porosity]] in subtidal grainy parts of sequences generally lacks early sparry cements; primary porosity preserved where marine fringing cement present
* Top and lateral seals may form where peritidal dolomite and evaporite progrades over [[third-order sequences]]
* Top and lateral seals may form where peritidal dolomite and evaporite [[Well_log_sequence_analysis#Parasequence_stacking_patterns|prograde]] over [[third-order sequences]]
An example is the Late Mississippian ramp reservoirs of the eastern and central United States.
An example is the Upper Mississippian ramp reservoirs of the eastern and central United States.
