Well symbols show production from this unit only. Numbers refer to unique well identifier. Depositional features were mapped by hand. Dashed lines show positions of cross sections. The zig-zag line indicates erosion of the underlying flooding surface.
Arrows show transport directions.
A number in a box refers to a paleogeographic feature depicted in the stratigraphic cross section. This key shows features present on the stratigraphic sections. In the Miocene study, the logs are the same digitized curves shown in the stratigraphic sections. In the Yegua studies, the logs are photographically reduced from paper originals. These sections indicate key stratigraphic surfaces, gapped faults cuts, depositional environments, major sand axes keyed to paleogeographic maps, biostratigraphic tops and paleobathymetric curve.
