Diagrams Shows A Normal Fault. Allan diagrams are useful for the production geologist but are subject to the uncertainty in the input data used. The image to the right shows simplified schematic diagrams of the offset of layers with the arrow representing the direction of slip along the fault plan which in three of the four examples are dip slip.
