Logging, X-Radiography, and Computed Tomography

In addition to vertical lithological descriptions at sampling locations, the goal should also be to develop isopach maps that show the lateral extent and variation of sediment layers. Other information, such as water content, density profiles, and results of grain size analyses should be incorporated to aid in these interpretation.
