Progradational clastic continental margins like the northern Gulf of Mexico can be divided into stable (e.g., Woodbine and Midway margins) and unstable (e.g., Tuscaloosa and Wilcox margins) types. In the unstable type, large-scale normal faulting at the margin modifies the original depositional geometry and allows local subsidence rates much greater than the regional subsidence (fig. 1). Sediments accumulating here can thus form a substantial part of the total basin fill (fig. 2). The growth faults individually propagate upward and their collective activity shifts basinward with the prograding continental margin.

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.
