Many complex structural features exist on the continental slope off eastern Louisiana that appear to have no land equivalents. Highly contorted near-surface structures overlie complex patterns of deposition. Salt or shale masses apparently intrude into sediments in horizontal planes as well as vertically. The total assemblage may account for new types of oil fields that may be very prolific.
A technique of analysis called "comprehensive interpretation" is used to illustrate structural anomalies. It involves carrying the entire geologic section in color-coded display of the 10-20 most reliable reflections available.
