Figure 7. (A) Seismic line 237 (CC ’) and (B) trace 243 (DD’) flattened on a Wolfcamp reflector in the basinal sediments overlying the Reinecke reef carbonates. Reflectors apparently onlapping the Reinecke buildup are actually basinal strata down- or baselapping against the Reinecke carbonate buildup from the east (right) with the contemporaneous shelf margin 50-100 km farther to the east (right). See Figures 3 and 5B for location of seismic line.
