The table below lists the procedure for classifying a trap.

The list below lists the procedure for classifying a trap.

# Determine the trap system: structural, stratigraphic, or fluidic.

#* '''If''' More than one element controls the trap Go to step 2  

#* '''If''' Only one element controls the trap Go to step 3  

# Determine the primary, secondary, and (if necessary) tertiary trap system.

# Determine the trap regime. What process formed trap closure?

# Determine the trap class. Which class best describes trap geometry, or which class describes compositional makeup of the reservoir or seal or fluid that creates or defines trap boundaries?

| Determine the trap system: structural, stratigraphic, or fluidic.

# Determine the trap family. What is the genesis of trap closure?

'''If''' More than one element controls the trap Go to step 2  

# If necessary, use intermediate groupings (superclasses, superfamilies, sub- classes, styles, subfamilies, styles, varieties) to give fuller descriptions.

'''Then''' Only one element controls the trap Go to step 3
