Objective(s):
|
1. Provide detailed reconstruction of the predrowning, drowning, and postdrowning evolution of the carbonate bank by linking the seismic stratigraphic record to the sedimentary record
2. Constrain the timing of this evolution, allowing age assignments of unconformities, sedimentary interruptions, sedimentary turnovers, and onset of drift deposition
3. Reconstruct and date bank to drift turnover |
|
