英文摘要: The style of faulting in offshore Louisiana, Gulf of Mexico, is characterized by short, arcuate regional and counterregional growth faults, which commonly form complex transfer zones above shallow, Miocene level salt bodies. South Timbalier Block 54 (ST54) constitutes one such area where a basinward-dipping regional and a landward-dipping counterregional growth fault form a convergent transfer zone. Structural interpretation using three-dimensional (3-D) seismic and well data reveals that the eastern and western flanks of the structure contain salt in the footwalls of the main regional and counterregional faults. The salt rises to a much shallower stratigraphic level in the central part of the transfer zone, forming a symmetric salt diapir. Secondary antithetic and synthetic faults adjacent to the two main faults and extending into the transfer zone accommodate slip between the main faults. Kinematic restoration of a series of north-south-trending cross sections across the structure show that upslope evacuation of salt is the result of sediment loading and growth fault movement, and the location of the transfer zone is possibly controlled by the allochthonous salt. The entire area is characterized by down-to-basin movement, with the major regional and counterregional faults displaying footwall and hanging-wall fixed deformation, respectively.
