    Six depositional sequences, each with a duration of approximately 1-1.5 m.y., have been identified in the Gzelian-Asselian successions of North Greenland, Bjørnøya, Spitsbergen and the Finnmark Platform. Correlation of the sediments in these widely separated areas is based on a refined fusulinid zonation. A total of four Gzelian and three Asselian fusulinid zones have been defined in the region and correlated to the Russian standard zonation. The depositional sequences are composed of restricted to open marine subtidal carbonates, Palaeoaplysina build-ups and minor evaporites. Each sequence comprises up to nine cycles, each less than 10 m thick, in the inner platform areas of the Finnmark Platform. No such cyclicity has been developed in the time-equivalent outer ramp settings of North Greenland, where each sequence comprises an upward-shoaling, 15-30 m thick unit. The sequences are interpreted to have formed in response to 3rd order fluctuations in relative sea level.
