墨西哥湾沿岸断层是正断层，但断层穹丘周围的断层除外。这些断层的所有水平分量在墨西哥湾沿岸海湾的积累使得沉积毯有必要发生相当大的水平位移。因此，区域性墨西哥湾沿岸断层模式及其许多局部变化被认为是由沉积毯进入盆地的区域重力蠕变造成的。当蠕动发生时，滑动沉积物脱离静止沉积物，形成边缘地堑，在靠近海岸的地方，形成不对称的下向盆地断层（具有反向拖曳力）和反向断层。
Gulf Coast faults are normal faults with the exception of those around fault domes. The accumulation of all horizontal components of these faults in the Gulf Coast embayment makes considerable horizontal displacement of the sedimentary blanket necessary. The regional Gulf Coast fault pattern and its many local variations are therefore thought to be caused by regional gravity creep of the sedimentary blanket into the basin. As creep takes place the sliding sediments break away from the stationary ones forming a marginal graben, and, nearer the coast, asymmetrical down-to-basin faults with reverse drag, and antithetic faults.
