==Chronostratigraphic charts==

A chronostratigraphic chart is a correlation chart with geologic time as the Y-axis and distance across the area of interest as the X-axis. A dip-oriented chronostratigraphic chart should be made. But we also should consider making strike-oriented chronostratigraphic charts, depending on the complexity of the stratigraphic section. A chronostratigraphic chart shows the following:<ref name=ch21r31>Mitchum, R., M., Vail, P., R., Sangree, J., B., 1977, Seismic stratigraphy and global changes in sea level, part 6: stratigraphic interpretations of seismic reflection patterns in depositional sequences, in Payton, C., E., ed., Seismic Stratigraphy and Applications to Hydrocarbon Exploration: AAPG Memoir 26, p. 117–133.</ref>
