During the Permian, how would the Kaibab Formation, consisting of sandy limestone, be depicted in a lithologic log?

The Kaibab Formation, primarily composed of sandy limestone, would be represented on a lithologic log by modifying the standard limestone symbol with sand to accurately reflect its unique composition. In a lithologic log, the goal is to depict the variations in rock types and their characteristics to convey a clear understanding of the geology in that area.

Sandy limestone contains both limestone and sand components, so a simple limestone block wouldn't adequately illustrate this mixture. Instead, adding sand to the symbol for limestone allows for a more precise representation of the actual rock type found in the formation. This approach recognizes the importance of depicting the characteristics of the rock accurately, which is essential for understanding the geological history and the environment in which the formation was deposited.

Proper lithologic logging is crucial for interpreting subsurface geological structures, resource mapping, and understanding depositional environments, which is why recognizing this modification is important in geology.
