3D model view of the Anadarko sedimentary basin from above

View of the Anadarko sedimentary basin from above, looking to the northeast. Colored surfaces represent the top of specific geologic units as mapped in the subsurface. The tops of deeper, older sedimentary units show a pronounce downward deflection and define the age of basin formation; younger, shallower sedimentary units (in light blue) overlie the deeper units without downward deflection and represent sedimentation that occurred after basin formation.
