The first step in stratigraphic trap exploration is a geometrical analysis of stratigraphic components of the basin fill. A geometrical analysis consists of (1) dividing the stratigraphic section into depositional sequences, systems tracts, and parasequences and (2) mapping their thicknesses. Correlation surfaces that are genetically significant, such as [[Unconformity|unconformities]], divide the stratigraphic section.

A geometrical analysis consists of (1) dividing the stratigraphic section into [[Definitions_of_depositional_system_elements#Depositional_cycle_vs._sequence|depositional sequences]], [[Definitions_of_depositional_system_elements#Systems_tracts|systems tract]]s, and [[Parasequences (fourth- and fifth-order sequences)|parasequences]] and (2) mapping their thicknesses. Correlation surfaces that are genetically significant, such as [[Unconformity|unconformities]], divide the stratigraphic section.

The articles in the See Also section discuss procedures and give examples of geometrical analysis.
