Abstract	A variety of ribbon carbonates of the Deh-Sufiyan Formation (Middle Cambrian) in Central Alborz Range of northern Iran are studied to provide facies characterization and paleoenvironmental interpretation of ribbon carbonates on shallow-marine carbonate platforms. Seven types of ribbon carbonates are divided based mainly on sedimentary structures, ichnofossils, and bed geometry, which represent deposition during different phases of storm-induced processes. The different features of the storm deposits in ribbon carbonates such as hummocky and swaley cross-stratification, planar lamination, and combined-flow-ripple cross-stratification were formed by combined flows. Identification and interpretation of ichnological signatures and the spatial arrangement of succession of sedimentary structures are used to further refine sedimentary interpretations of parameters such as wave energy, substrate properties, variability in sedimentation rates, and proximality-distality trends of a wave-dominated marine ramp sequence. Successions from individual storm events reflect deposition during increasing combined oscillatory and unidirectional flow succeeded by the waning stages. The study provides depositional processes and models of various ribbon carbonates that may be useful for facies interpretation of ribbon rocks elsewhere.
