This chart was created to explain the Stratigraphic Units used for the Type Logs Project. In many cases many of the units that are listed in this chart are considered "informal", i.e. Excello Shale Member is used in many of the Tops for Kansas Wells, but is not listed in the Official Kansas Stratigraphic Units Chart. Many of the Stratigraphic Units that are mentioned in the Type Logs Project are units that Geologist are most familiar with and can be traced back to outcrops or to core descriptions. To follow this logic this web site was created to display many of the measured sections or core descriptions that have been published by Kansas Geological Survey and will be used here to represent the Stratigraphic Units that are part of the Type Logs Project.
