Mapping age-specific isopach thicks in the northern GOM basin defines laterally shifting sites of maximum deposition (Figure 4-4). Methods of mapping are clearly presented in Tearpock and Bischke.<ref name=ch04r94>Tearpock, D., J., Bischke, R., E., 1991, Applied Subsurface Geologic Mapping: Prentice-Hall, 648 p.</ref>
