Changes

Using this age model to calibrate each depositional cycle helps us calculate geologic rates, such as rates of rock accumulation and burial and thermal heating rates of the stratigraphic section.

Dating within the wells is based on key biostratigraphic marker species for the deep-water environments of the GOM basin. Interval B is characterized by high rates of sedimentation associated with abundant gravity-flow sand deposition. It is followed by interval C, characterized by slow sedimentation and deposition of regionally effective top seal.
