FIG. 45. Structure formed by oblique bedforms with pseudorandom plan-form geometry.
RECOGNITION: This structure is similar to that shown in Figure 43, but the pseudorandom plan-form geometry adds complexity and causes scatter of the bounding-surface poles. Recognizing that the complexity arises from spatial differences in bedform morphology, rather than from temporal differences in bedform morphology or behavior, requires three-dimensional exposures that include extensive horizontal sections.
ORIGIN: This structure differs from that in Figure 43A only in having a more random plan-form geometry.
