Each depocenter has a unique depositional history that reflects the integration of all responses to depositional processes and environmental factors, including tectonics, climate, sediment supply, and sea level variation. These factors result in cycles of deposition: the sediments accumulated during each cycle are the depositional sequence. Integration of multiple data sets, including (1) seismic reflection profiles, (2) biostratigraphic analyses, (3) wireline logs, (4) cores, and (5) detailed measured sections, helps us define the depositional sequences and interpret primary factors affecting formation of each cycle. Precise mapping of each depositional sequence within each depocenter requires careful data integration.
