Lithology log response

WebMapping Gamma-Ray Log Response Each gamma-ray log records changes in the vertical, time dimension at a single location. However, the mapping of the gamma-ray response of a specific stratigraphic unit can show areal changes that reflect paleogeography and regional patterns of depositional environment.
