Figure 5--A dip cross section modified from that of Baker and Scott (1985) shows depositional environments inferred for the Edwards shelf margin. The Word field complex consists of grainstones that formed in beach ridge and sand-flat settings. This depositional model is valuable because it generally shows the facies relations and correctly points out that there is significant development of shallow-water Edwards facies far seaward of Word field; however, the model does not convey the stratigraphic variation within the upper Edwards and thus does not portray correctly the details of the interrelationships of the Edwards facies.
