Delta Systems II
Review of the process framework and associated morphology and sediment distribution patterns in modern deltas shows that three basic process suites determine delta geometry and distribution of framework sand facies: (1) sediment input, (2) wave energy flux, and (3) tidal energy flux. Major remobilization and displacement of bed-load sediment from the delta front may generate a coupled, but depositionally distinctive, submarine slope system. A tripartite classification of delta systems, based on dominance of depositional process, is shown in figure 1.

Structural and Depositional Styles of Gulf Coast Tertiary Continental Margins: Application to Hydrocarbon Exploration
The structure and genetic stratigraphy of the Gulf of Mexico continental margin are inextricably intertwined. As hydrocarbon exploration and exploitation advance into the deeply buried Tertiary basin fill, interpretation of the complex depositional and structural styles of the outer shelf and upper slope setting will increasingly challenge the interpreter. This publication provides a coherent summary of the key concepts, models, and tools that are needed to meet this exploration challenge, and includes chapters on: basic principles, submarine slope systems, models of growth faults, mechanics of diapir growth, petroleum traps, and techniques on analyzing normal faults and balancing cross sections with extended strata.
