Figure 24-Sequence of interpreted seismic profile and detailed drawing across the Oligocene-Miocene detachment province on the south-central Texas shelf. The middle Miocene perched detachment (center) is interpreted as an analog for the Vicksburg shale-based detachment; it is connected downdip to the deeper Oligocene-Miocene detachment interpreted as an extensive salt weld. UM = upper Miocene, MM = middle Miocene, LM = lower Miocene, OL = Oligocene. See Figure 2 for location.
