San Andres Formation (Permian) outcrops in Last Chance Canyon are interpreted to contain two large-scale, fourth-order depositional sequences, upper San Andres sequence 3 and upper San Andres sequence 4. Embedded within each of these sequences are numerous higher frequency sequences. Reciprocal siliciclastic/carbonate sedimentation patterns enhance the recognition of cyclicity within both large-scale sequences and within many of the higher frequency sequences.

Upper San Andres sequence 4 contains at least 12 smaller scale sequences that occur in landward-stepping, vertically stacked, stratigraphically rising seaward-stepping, and stratigraphically falling seaward-stepping geometric patterns. In outer-ramp/slope environments, landward-stepping, high-frequency sequences of the lowstand to transgressive...
