warm-water carbonate platform developed across the east-ern part of the present Arctic archipelago of Svalbard. The platform initiated in the Moscovian on an uplifted fault block (Ny Friesland High) and progradated during the Late Moscovian to Early Kasimovian into the adjacent Camp-bellryggen Basin (central Spitsbergen). The fossiliferous platform strata are characterized by a pronounced cyclicity formed by stacked parasequences, which consist of deWned, subtidal to supratidal facies-set successions reXecting a general shallowing of the depositional area. Up to 17 of these shallowing-upward cycles, bounded by distinct dis-continuity (marine Xooding) surfaces due to the recurrent emersion and subsequent Xooding of the platform surface, have been recognized within the platform strata. The stacked cycles are the result of global, glacio-eustatic, high-frequent and high-amplitudinal sea-level Xuctuations with eccentricity periodicities caused by ice volume changes during the Gondwana Land glaciation. Based on system-atic changes of the cycles (thickness and internal facies composition), the upper part of the platform strata is interpreted as a progradational parasequence set of a late highstand system tract.
