Three facies units are clearly delineated by the log signature. Note also several coarsening-upward cycles indicated in the log signature of the lower facies unit. Line of cross section is shown on Figure 21.1. Figure 21.10 Generalized schematic diagram illustrating the sequential development of the estuarine valley-fill sequence in the Viking Crystal Field, central Alberta. Line of cross section is shown on Figure 21.1.
All logs are gamma ray.
Line of cross section is shown on Figure 21.1. All logs are gamma ray. This core penetrates that part of the Viking sequence that is entirely above the sequence boundary.
