Lower famenian deposits environments of the Central Khoreyvers refogenic zone

A complex study of the Lower Famennian carbonate deposits in the Central Khoreyvers reefogenic zone are considered. It was found that five facies zones were distributed in the area during Early Famennian. A frequent fluctuation of the sea level and water salinity were characteristic for the Early Famennian paleobasin. New data allow to give a more precise definition of the Early Famennian paleogeographic map for this area.
