Fig. 4.9.— Sediment types and patterns on an offshore high in the Persian Gulf. Windward-leeward asymmetries such as this one
are probably common in the geologic record but are difficult to recognize in outcrops because of insufficient coverage, seismic data are
often more effective. After Purser (1973), modified.
