Geological maps can not be considered complete until there is at least one cross section has been created to show the geology below the surface. [[Cross section]] describes the structure of a region that is much clearer than a planimetris map.cross section can be drawn in addition to a map of the fair copy,and simplified again as an illustration in a cross section of the report.it can show geological formation boundary at depth,and can also be used to display a fault, cleavage and surface folds on the map.
